First of all, it is important to know that we are not talking about your camera when we refer to focal length. The camera of course plays an important role, but it is the job of thelensto take the light and focus it at a particular point. The light from the scene hits the object ...
The mirror formula, which gives the relation between image position, object position and focal length of the mirror is, 1f=1v+1u Here, f is focal length of mirror, v is image distance from mirror and u is object position from the mir...
What is a land breeze? What is analog broadcasting? What is atmosphere? What does a weather vane tell you? What does km stand for? What is a kinematic link? What is the angle of repose? What is a catapult? What is the focal length of a plane mirror?
What changes, if any, do you expect in their focal length? View Solution Q4 A spherical mirror and a spherical lens each have a focal length of, -15 cm. The mirror and the lens are likely to be : (a) both concave. (b) both convex. (c) the mirror is concave but ...
Question If Joshs face is 30.0 cm in front of a concave shaving mirror creating an upright image 1.50 times as large as the object, what is the mirrors focal length? A 12.0 cm B none of these answers C 20.0 cm D 70.0 cm E 90.0 cm...
Still, the In-Camera HDR function is a great feature because the camera controls everything. For example, with the In-Camera HDR function on the Canon 5D Mark III, we can use Mirror Lock-up, set the camera to a 2-second timer, and set our bracketing sequence with a number of frames...
A concave lens with a more focal length. Two lens holders. One thick and one thin optical needle. A knitting needle. A half-metre scale. What is difference between concave mirror and concave lens? A concave mirror is opaque whereas aconcave lens is transparent. A concave mirror can form ...

Since spherical abberation is maybe the most common mirror problem, I was wondering if anyone knows any workarounds. As stated in my previous post, what you are seeing is likely spherochromatism. Moving the focal plane won't fix that. ...
Typically, the mirroring surface area is a thin finish of silver or lightweight aluminum on the glass. Product specifications for optical mirrors consist of size, the radius of curvature, density focal length, and surface high quality. The diameter or elevation of an optical mirror is measured ...
