Yeah I don't think incoherence is an issue either. I remember my professor saying Young did the two slit experiment with sunlight because it was the only way he could ensure the waves would be in phase, since its just one source "separated into two."
But it does infact turn out to be...
I'm confused differently now. You say...
"A source can be emitting many photons, which may be of different frequencies (non-monochoromatic) or of different phases (incoherent). Either effect will wipe out interference effects."
It's been to my understanding that a single source (such as a...
Hello, hope you all had a good summer
The questioned posed is:
Why are the two-source interference equations not valid for light from an incandescent bulb that shines onto a screen with a single slit, and then the light shines onto a screen with two slits in it and the light from the two...
Thanks for the solution. But I don't understand why your integral is so much different from my textbooks. I'll have to bring it up in discussion. Thank you though.
The problem gave me that equation.
But when you integrate it, it comes out to be:
W = -p_i*V_i * ln(V_f/V_i) = -p_f*V_f * ln(V_f/V_i)
I even have a page in my physics book that derives it for me. But according to masteringphysics, that's wrong.
But if I draw a P-V graph, it doesn't look like...
Homework Statement
A cylinder with initial volume V contains a sample of gas at pressure p. The gas is heated in such a way that its pressure is directly proportional to its volume. After the gas reaches the volume 3V and pressure 3p, it is cooled isobarically to its original volume V. The gas...
I dunno, apparently it's wrong. Cause that's what I initially plugged in. It told me k is not a variable, and I should use R, which is lame that it didn't say that in the first place. I converted k to R using avogaddies number and its still says its wrong.
Homework Statement
n_1 moles of a monatomic gas and n_2 moles of a diatomic gas are mixed together in a container.
Derive an expression for the molar specific heat at constant volume of the mixture.
My answer can only use the variables n_1 and n_2, and I'm assuming constants.

I'm not positive what you mean by "eating."
But, I figure the gas in B will have to exert the same amount of energy it gained from the weight of the piston to raise it back up. In which case, I figure the temperatures are equal.
Homework Statement
Two 800 cm^3 containers hold identical amounts of a monatomic gas at 20 degrees C.
Container A is rigid.
Container B has a 100 cm^2 piston with a mass of 10 kg that can slide up and down vertically without friction.
Both containers are placed on identical heaters...
Homework Statement
Consider two light rays propagating from point A to point B in the figure, which are 3(lambda)/4 apart. One ray follows a straight path, and the other travels at a 60 degree angle to that path and then reflects off a plane surface to point B. Both rays have wavelength...

Homework Equations
How much time does it tank to half empty the tank? find t_(1/2).
