Indian Institute of Management Lucknow (abbreviated IIM Lucknow or IIM-L) is a public business school in Lucknow, Uttar Pradesh, India. It was established in 1984 as the fourth Indian Institute of Management (IIM) by the Government of India. IIM Lucknow offers post-graduate diploma, fellowship and executive programs in management. It is recognised as an "Institution of Excellence" by India's Ministry of Human Resource Development. IIM Lucknow also serves as the mentor institution for the newly established IIM Jammu, IIM Rohtak and IIM Kashipur. It also served as a mentor institute to IIM Sirmaur till 2018.The institute is on a 200-acre site in the northern outskirts of Lucknow. It also has a second campus on a 20-acre site at Noida exclusively for one year full-time MBA program (IPMX), Two-year PGP for working executive and executive education. The admission for the two-year PGP and fellowship programmes is done through Common Admission Test (CAT), while GMAT score is used for International Programme in Management for Executives, a one-year full-time residential programme equivalent to an MBA program, while admission to the Two-year PGP for working executive program is done based on GMAT score or a competitive written examination conducted by IIM Lucknow. The shortlisted candidates based on GMAT or the written examination go through the Writing Ability Test and Personal Interview (WAT & PI) to get final selection. The programs are accredited by the global accreditation body AMBA and AACSB. The institute has tie-ups with 24 leading B-schools across the world for student exchange. A number of b-competitions, cultural and sports events are organised by various clubs, academic interest groups and committees throughout the year.
I want to make an experiment about the refractive index of ice but this time I want to use different temperatures. (for example with -15 C ice and with -1 C ice) When I tried to search on the internet I couldn't find any specific formula or any article because I guess I couldn't explain what I...
I've been playing around with this for quite some time now this morning but can't get the last bit out. I defined the time functional to be $$T[y] = \int_{x_1}^{x_2} \frac{\sqrt{1+(y')^{2}}}{c(y)} dx$$ which follows from consideration of the time taken to cover an infinitesimal section of arc. I...
I emphasize that I am not posing a rhetorical question, and am not trying to make a political statement (and would ask all respondents to steer clear of politics), but would genuinely appreciate knowing whether the report in question is considered valid by those in the field who are impartial...
In the image attached, How is it that the angle shown is 2A? And what exactly is the position of min deviation? Why does it have to be in the given position as shown?
Thanks in advance!
Since ##\nu## is contracted, we form the scalar product of the metric and inverse metric,
##g_{\mu\nu}g^{\nu\lambda} = (\vec{e_\mu} \cdot \vec{e_\nu}) \cdot (\vec{e^\nu} \cdot \vec{e^\lambda}) = \vec{e_\mu} \cdot (\vec{e_\nu} \cdot \vec{e^\nu}) \cdot \vec{e^\lambda} = \delta^\lambda_\mu##

Any one can help deduct the process to obtain the following equation?
n= squart(ε*μ), n=refractive index, ε=relative permitivity, μ=relative magnetic permitivity.
I am reading a book relating to spectroscopy, and saw the above equation. I am really interested how the scientists got this...
I was just thinking about this earlier and couldn't come up with a good enough resolution. I'm guessing it's a matter of convention more than anything. If we have ##x^{2} = a##, taking the principle root of both sides gives ##\sqrt{x^{2}} = \sqrt{a} \implies |x| = \sqrt{a}##.
Yet evidently if...
A thin lens has an upper radius of curvature 𝑅1 and a lower radius of curvature 𝑅2. When the lens is completely surrounded by air, it has a focal distance 𝑓. The lens is then placed in the interface between air and water inside a vessel (see figure). Calculate the refractive index for the glass...

Apologies it's been a little while since I've done this, but I believe the rule is, that if the object is not a tensor you can not rename the dummy index?
For example, i have the action

A is the angle of refraction (~60 degrees) and Dm is the angle of minimum deviation that was different for each of the spectral lines associated to one of the six wavelengths measured.

Hey everyone .
I was recently studying about fiber optics and it had a little to do with graded index fiber. And its given that the refractive index of the core changes from the axis to the cladding .
So , my question is , how is that fiber designed ? It must be quite complicated to carefully...
I first determined ##E_{U - B}## by using the second equation listed above: $$U - B = (U - B)_0 + E_{U - B}$$ $$8.15 - 8.50 = -0.45 + E_{U - B}$$ Then since the ratio to the B-V color excess is known, I solved for that and obtained ##E_{B - V} = 0.14##. Using the ratio of total to selective...

Hi,
I spent some time during my PhD with the task of indexing TEM diffraction patterns, usually made with selected area diffraction. All available software I found online was either too complicated or too expensive (or both). So I decided to make my own: https://www.odpin.com

The presence of the cosmological constant produces a flat spacetime universe with Ω = 1. There is also the curvature index of space k, which can be +1, 0, -1. But it is possible to have any of these values of k with Λ > 0 or Λ < 0. How is the curvature of spacetime determined by Λ different from...
Hi,
I was doing this question and I was slightly confused as to whether I ought to just substitute n = \gamma (the adiabatic constant) into the equation? The answers don't do this, but I was wondering why it was wrong for me to do so? This was only a small fraction of the question (which was...
Hi. I want to look up the H index of a few authors I am interested in using google scholar or some other site that i don't need to pay for access. But can't see how to do it. Can anyone help?

Suppose I have a velocity field V^a which looks like < \partial x / \partial t , \partial y / \partial t , \partial z / \partial t > and I use the metric tensor to change it into a covector field V_a = g_{ab}V^a. Does it then represent the same quantity or < \partial t / \partial...

how to write a summation with decreasing index

how do we write the above for index to go from n to 1 down wards
Hi,
I know that, at least formally, the index of a radical should be positive and integer. That is if I introduce
\sqrt[x]{2}
I need to assume x\in \mathbb N and x>0.
However, my calculator has no problem in calculating the radical for any x\neq 0, say x=-\pi.
The result it gives is based on...
For class I conducted a experiment where I made sugar solutions, poured them into a glass prism container and used a laser pointer to find the refractive index. However, while typing in my results I realized I found the angle of deviation instead of the minimum angle of deviation since I didn't...

For the life of me, I can't figure out why my program won't update the index variable. I've tried setting the index to 0, and then to -1, and to the size of the arrayList - 1. I'm trying to use the index to get the previous and next flashCard in the arrayList to show up.

Consider a thin transparent plate surrounded by air. The plate's refractive index is exactly the same as the air's, but it does have a small loss (say of the order of 1%).
Let the plate be vertical and normal to our "page" or your computer screen. A laser beam passes through the plate at an...
Hi.
I came across the following statement , which seems wrong to me.
Λμρ = ( ΛT )ρμ
I have it on good authority (a previous post on this forum) that (ΛT)μν = Λνμ so I am hoping that the first equation is wrong ? It looks like the inverse not the transpose ?
The equation Λμρ η μνΛνσ = ηρσ is...

Hello PF,
I'm reading a paper for a project. In the paper they derive an equation for the effective refractive index ##n=\sqrt{\epsilon^{e} \mu^{e}}## of two stacked layers ##(n_1^2 = \epsilon_1 \mu_1, a)## and ##(n_2^2 = \epsilon_2 \mu_2, b)## where ##a,b## are the lengths and in my case...
red marker part in my book is very confusing.
It says you will not succeed to create index by that.

By observing that red is the outermost color of the rainbow it is possible to conclude the refractive index of water, n, is lower for red than for blue. However, why is n lower for red? This seems to be answered by the Drude dispersion model, with a resonance in the ultraviolet region, but I...
