m=-0.193m/0.675m=-0.286 mtotal=-2.5*-.286=.715 thank you!

Oh my goodness, that was a silly mistake. I was wondering why it was so low. Thanks for your patience! λfilm=480 n=1.18 !

Oops, I meant to correct that on the last attempt. Let me try again. Lens 1: 1/.15m=1/.21+1/di d-i=-0.525m m=-0.525m/0.21m=-2.5 Lens 2: do=1.20m-.525m=0.675m 1/.15=1/0.675m+1/di d-i=0.193 m=-0.193m/1.2m=-0.161 m-total=-2.5*-0.161=0.402 I hope that's correct!

I am not sure why one equation is for diffraction grating and the other is for the double slit experiment. I think you would be more qualified to answer that. Are the dimensions of the setup sufficient to use an approximation to get the distances more directly? I'm not sure what you mean...

What do you mean, "was there a question in all that?"

We covered it briefly, but I don't remember my professor saying anything about the 1/4 factor. So, is this correct? 120nm=1/4λfilm λfilm=30nm n=λvacuum/λfilm=565nm/30nm=18.8

Lens 1: 1/.15m=1/.21+1/di d-i=-0.525m m=-0.525m/0.21m=-2.5 Lens 2: 1/.15=1/(.21+1.20m)+1/di d-i=0.171m m=-0.171/1.2m=-0.143 m-total=-2.5*-.143=0.357

Homework Statement You shine a green laser pointer (l = 535 nm) on a diffraction grating that contains 1.0 x 104 lines/cm. When projected onto a screen that is 5.0 m away from the grating, how far apart will the zeroth-order and first-order bright spots be? Homework Equations sinθ =...

Homework Statement In a version of Young’s double slit experiment, the slits are separated by a distance of 1.0 mm. The light from the slits is observed on a screen that is 12 m from the slits. If the wavelength of the light is 550 nm, what is the linear distance on the screen between the...

I am really confused about this question. I've read the chapter and what you wrote. The only equation in the book that I see is: n=λvacuum/λfilm=565nm/? I am not quite sure what to do with: nglass = 1.52 or t=120nm or how to find the wavelength of the film.

On my second attempt I got an mtotal of 0.357

I got -.509 on the second try. Hopefully that is correct.

Homework Statement A pair of eyeglasses has an index of refraction n-glass = 1.52. It is covered with an antireflection layer that has a thickness of 120 nm and an index of refraction that is less than n-glass. If the antireflection layer is designed to minimize reflection in the middle of...

Homework Statement Two identical converging lenses have focal lengths of 15 cm and are aligned on the same principal axis. They are separated by a distance of 120 cm. An object sits a distance of 21 cm to the left of the left lens. What is the total magnification of the two lenses...

Homework Statement An object is in front of a converging lens with a focal length of 11.0 cm. The lens produces a real image located 25.0 cm from the lens. If the lens is replaced by a new lens (in the same position) that has a focal length of 32.0 cm, what is the image distance of the...
