This is a problem from Boyd Nonlinear Optics chptr 1 problem 2.
Homework Statement
Numerical estimate of nonlinear optical quantities. A laser beam of frequency ω carrying 1 W of power is focused to a spot size of 30μm diameter in a crystal having a refractive index of n =2 and a second order...
My intro QM class is currently using this text, but I find that there is not very many worked examples of problems, and there are no solutions for the chapter questions in the back.
My class assignments are not based out of the book, so I was wondering if anyone knew of a solutions manual I...
I'm sorry if I came off as offended and defensive. I wasn't trying to.
I did notice after that you had the same identity written down as tiny tim, but I had already posted twice and didn't want to go back and post again.
I'll respond more carefully in the future so this doesn't happen again.
I am aware of the orthogonality relations, however I am not familiar with how they are derived, that is not covered in my textbook unfortunately. I do know that sin and cos are orthogonal on the interval -L to L, but they are not orthogonal on the interval 0 to L (according to my text), so this...
Homework Statement
all i really need to do is solve the integral:
\int-3*sin(\frac{n*pi*x}{L})*cos(\frac{8*pi*x}{L})
from x=0 to x=L

The Attempt at a Solution
I'm not very sure where to start with this. Any help would be appreciated.
Sound waves are longitudinal and water waves are transverse. The median in which they propagate is matter.
What you seem to be interested in is string theory(I noticed you changed your original post) I would suggest you read a book called the elegant universe by Brian Greene.
Also What...
The OP stated that he means the mass of the system, which means everything inside the plane. The Planes mass itself cannot change.
I think the problem here is that people Aren't distinguishing between mass and weight. If you look at the system from the outside, the force required to hold up...
if you think about it in terms of Newtons law F=ma then it makes sense.
to accelerate the entire system by, say, 20m/s^2 then the force required is F=(m-plane+m-people+m-fly +...)*20m/s^2.
First of all, you have to define "adding mass to the plane". If you mean does the fly add mass to the plane in terms of mass being accelerated:
if the fly were hovering on take off, the fly would not add mass, but it would add weight, due to the air being pushed down by its wings to lift itself...
question 1
There is definitely a correlation between colors and musical notes, as they are both waves. Light is an electromagnetic wave, which means it is oscillating electric and magnetic fields. Sound is a wave as well, although in this case a longitudinal wave, not a transverse wave like...
The energy of the photons your body absorbs is still much less than that of the sun. You'll do more harm standing outside than using a Bluetooth headset.
i think if you had a 100PSI compressor, you could raise the pressure by 100PSI.
the volume would remain the same, so T would go up by the same factor.
100PSI is 14 times atmospheric pressure, so the temperature would increase by a factor of 14.
but i'm not 100% sure. hopefully someone else...
it might help if you draw electric field lines running from the positive to negative charge to help yourself visualize what is going on.
if you don't know what electric field lines are there is a perfect example of how to draw electric field lines between a positive and negative charge...
Homework Statement
a massless string of negligible thickness is wrapped around a uniform cylinder of mass m and raidus r. the string passes up over a massless pulley and is tied to a block of mass m at its other end.
the system is released from rest. what are the accelerations of the block...
okay i did know that, but i don't know how to find the root mean square of each waveform.
the problem is in my lack of knowledge of statistics it seems...
Homework Statement
3. Consider the narrow triangular voltage pulse V(t) shown in the figure.
i can't paste the function but its a piecewise function of the form:
V(t)={1+(1/a)t from -a <=t<=0
{1-(1/a)t from 0<t<=a
{ 0 otherwise
(a) Find and sketch the spectral content...
I'm in a second year physics course, and were studying Rutherford scattering.
I'm not having any trouble with the physical or mathematical concepts, I'd just like a more precise definition of the phrase "impact parameter". I searched google, and my notes and textbook but couldn't really find...
i've heard people describe it as physics is the science behind engineering.
if you look at it that way, which makes sense, because many of today's technological advances comes from the field of engineering without the study of physics our standard of living would not be the same without phyics.
i have been thinking about graduate school, but what sort of marks would i need to get into any graduate schools?
from what i've heard its very competitive, but i would love to do that.
the triangulation method would be very inaccurate but they measure very small angles.
for example, most astronomical measurments are done in arcseconds, where 1 arcsec = 0.000277777778 degrees.
calculations in arcsec's are done to small numbers. from what i've seen in my limited astronomy...
dude don't worry at least you gave it alot more thought then some people would have.
just remember with vector quantities like accelaration and displacement and velocity, direction matters.
