Thanks again; I found 2 angles for the last problem - would the difference be the angular separation between the primary and secondary images? Thanks

Theres a second part of the question that I'm confused about: Steve also sees multiple images of light due to constructive interference from the light that diffracts through different gaps between his eyelashes. The most prominent secondary images occurs at an angle such that the path lengths...

What would the slit width a and the variable m be, then? I don't think we learned that in class yet. Thanks for your help!

Homework Statement Diffraction and interference occur for wave phenomena such as light and water waves as well as sound waves. During a lecture on diffraction, Steve's eyelids droop,meaning that he closes his eyes until he is looking out through his eyelashes. Then, a green light (lambda= 6...

Homework Statement Hi, I'm in desperate need for help. Any guidance in the right direction will be appreciated: Heat Q flows spontaneously from a reservoir at 394 K into a reservoir that has a lower temperature T. Because of the spontaneous flow, thirty percent of Q is rendered unavailable...

Ok, so I'm still pretty confused. I'm trying to work this out, and I've made this into a system of equations. Maybe you can take a look: 24-x = 1/2 (9.8)t^2 + 21.7t x= 1/2(-21.7t) + 0 I know this is wrong, so I'm just confused where in my equations I'm wrong. Thanks again.

I know that both of them will share the same t, but that still doesn't make any sense to me.

Here's the question: A ball is dropped from rest from the top of a cliff that is 24 m high. From ground level, a second ball is thrown straight upward at the same instant that the first ball is dropped. The initial speed of teh second ball is exactly the same as that with which the first ball...

Hi, I'm having trouble on the following question: A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 3 excited state. The ion returns to the ground state by emitting two photons. What are the wavelengths of the lowest energy photon and...

Ohhhh I understand now! Thanks!

Hmm - the exact question is: What is the minimum nonzero thickness of the film in a spot that looks the following colors because of destructive interference? a. Yellow b. Violet I didn't enter it first because I figured the steps for solving both would be the same. Thanks for your help, again.

Should I maybe try t = lambda x 0.25? Or, perhaps, my lambda value is incorrect. I'm dividing by 1.40 (to reprsent the gasoline). Is it possible that I should divide by 1.33 first? I'm feeling really lost on this one, I don't understand why Webassign keeps marking it wrong.

Great, I understand it now. Thanks so much!

Oh, the 2 shouldn't be there, because its constructive interference, not destructive. Does the m=3 make sense, too? I'm not sure what the maximum value can be - would it be 90 degrees (pi/2), because that's the maximum value that sin can be?

Hi - I'm trying a problem on diffraction grating, and I keep on getting stuck. Maybe someone can help me figure out the last step: Three, and only three, bright fringes can be seen on either side of the central maximum when a grating is illuminated with light ( wavelegnth = 490 nm). What is...
