okay here are the equations;
An object is 17.3 cm from a concave mirror of focal length 8.10 cm. (a) What is the image distance? State your answer with the correct sign. (b) What is the magnification? (c) Is the image upright or inverted? (i know what the answer is, i just dont get how to get it.)
You wish to use a concave mirror to produce a virtual image that is three times the size of an object. (a) Which will be closer to the mirror, the image or the object? (b) If the object is 22.0 cm from the mirror at this magnification, what is the radius of curvature of the mirror?
A mirror of focal length 26.6 cm creates an image with magnification −0.350. What is the image distance?
if anyone could explain how to do it to me then that would be great!
many thnxs to those who help!!! i really appreciate it.
