AI Thread Summary
To calculate the spectral intervals for the Lyman, Balmer, and Paschen series of the hydrogen atom, the correct energy level transitions must be identified. The Lyman series involves transitions from n=2 to n=1 for λmax and n=∞ to n=1 for λmin. For the Balmer series, the transitions are from n=3 to n=2 for λmax and n=∞ to n=2 for λmin. The provided frequency formula is relevant, but clarity on the specific energy levels for each series is crucial for accurate calculations. Understanding these transitions is essential for determining the spectral intervals correctly.

Homework Statement



Calculate the spectral interval (λmax, λmin, and Δλ) in which all the lines of the Lyman, Balmer, and Pashcen series (excluding their continuous parts) of the H-atom are found.


Homework Equations



Here is where I am confused.. do I use the Balmer's formula for H?

frequency = [1/4 - 1/n^2] * 3.29*10^(15)s^-1

The Attempt at a Solution



The problem is.. I don't know what energy levels these series correspond to? Is this something I am just supposed to memorize??

For Lyman series, transition from n = 2 to n = 1 for λmax and n= ∞ to n = 1 for λmin.
Similarly for the other series.
 


Is the equation I provided correct in this case??
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
