A stationary light source S wit ha natural frequency Fo is viewed in a mirror M by a stationary observer O. The mirror moves away from the observer wit ha velocty of Vrel << c a) what frequency of light is recorded by a detector attached to the moving mirror because Vrel << c classical may...

I have a few mirror questions. I missed class and didnt get the formulas to do these. If some one could help me out it would be appriciated. The formulas I have in my notes are 1/f = 1/do + 1/di and hi = (ho * di) / do. I don't think I have enough info to use these formulas and I am guessinf...

A piece of glas has an index of refraction of 1.5. The ends are hemispheres with radii 2 cm and 4 cm, and the distance that separates the centers of the hemispherical ends. A point object is located in air 1 cm from the left end of the glass. Find the location of the image of the object due...

Suppose you want to take a photograph of yourself as you look at your image in a flat mirror 1.8 m away. For what distance should the camera lens be focused? You must be ½ the total distance away: since the angle of incidence is equal to the angle of reflection, the distance needed to get a...

determine the minimum height of a vertical flat mirror in which a person 5'0'' in height can see his or her full image. I have absolutely no idea how to solve this type of problem... Since we don't know the distance between the object and the mirror, how in the world can we calculate the...

This is driving me crazy I am ready to either bash my head through a window or kill something. I can't get any of these homework problems and I have no idea why... These are webassign problems so it tells me if its the wrong answer but naturally doesn't tell me what I'm doing wrong... so I am...

i was wondering why is it that in a mirror that my image is fliped but not upside down, why is it in just one plane.

Sure, everyone knows that the angle of incidence equals the angle of reflexion. My question is rather aimed at the atomic level. What is the interaction between electromagnetic radiation and matter? Why can a layer of metal (a mirror) reflect light? Does the interaction occur at the electron...

Hi, I've asked someone to make me a parabolic mirror for a robot and they want to know the 'mirror gain' i would like. Does anybody know what 'mirror gain' is? thanks

A converging lens (convex) and a concave mirror, both of focal length 5.0 cm, are arranged with their axes in line. The lens and the mirror are 10.0 cm apart and a candle is placed 3 cm infront of the mirror. By using a ray diagram or some other metho, find the location of all the images...

Well, here is the problem: A girl has her 2-cm high eye 12 cm directly in front of a concave mascara mirror or focal length 18 cm. Where is the object located, and what is the magnification? I'm really lost on this one. EDIT: Sorry, I just realized this would be better suited for the...

If you have a convex mirror, and you point a light at it horizontally, does the light always reflect through the focal point? (the point halfway on the line connecting border and the center, parallel to the light's initial path) I remember learning this, but I think of a mirror in the shape...

if a double concave mirror with a focal length f = -20 inches is used , where does the image seem to be located , if the image is 30 feet away from the lens first i converted the 30ft to inches and got 360inches used formula 1/p + 1/q = 1/f .0028 + 1/q = -.05 1/q = -.053 q = -18.9...

Mirror due Midnight! Problem 32. A concave spherical mirror can be used to project an image onto a sheet of paper, allowing the magnified image of an ulluminated real object to be accurately traced. If you have a concave mirror with a focal length of 16 cm, where would you place a sheet of...

Can someone get me started on this, I know how to work a diverging lens and a concave mirror, just not together. The problem: A concave mirror with a radius of curvature of 20.0 cm is placed 25.0 cm from a diverging lens with a focal length of 16.7 cm. An object is placed midway between the...

Greetings All, I am attempting to develop a software simulation of the dynamics involved in machine figuring concave parabolic telescope mirrors. As a member of the amateur telescope making community, we currently don't have any tools to do this other than the "trial and error" method...

I am looking for a mirror (11" x 14") that reflects only shades of gray. Ideally the reflection would be like a black and white photo (The subject's reflection would be "black and white"). Is such a mirror available? If not, can one be made? If so, by whom? Thank you for your assistance.

How much force (in Newtons) is exerted on a mirror when a 12.0W laser beam of red light (675 nm) strikes the mirror normal to its surface? (Assume no light is absorbed) How how how how? kthx

I hope this is the correct place to put this... There are certain types of sunglasses which reflects like a mirror on one side, and normal shades on the other. I understand that this is due to a coating of some mercury salt on the lens, but what is the exact physical explanation of this...

A few questions about mirrors: 1) How much light (as a percentage) does your average home mirror reflect? 2) How much light (as a percentage) does a very high quality mirror reflect? 3) How much does a very high quality mirror cost? Thanks.
