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.
