2.Can virtual image be photographed?
3.what is the unit of magnification?
4.Out of speed , frequency and wave length which remains same after reflection?
5.Give two applications of convex mirror?

Answer 1

1. The distance between ending points of mirror...
2. No.
3. Unit less
4.Speed , frequency.

Answer 2

1)Centre of curvature, focus point, and hence radius of curvature and focal length all lie at infinity..
2)Yes.Any camera that's capable of photographing actually object is also capiable of photographing real and virtual image..
4)May be all remains the same..
5)Convex mirrors are used in sunglasses and vehicles..
