Question

If you can't answer all four, then please answer c and d. Try to answer mathematically.

If each statement below is true, prove the statement. If not true, explain why not.
a) The image of an object reflected by a convex spherical mirror is always upright and virtual.

b) If an object is placed in front of a converging lens, the image is always inverted and real.

c) The image of an object reflected through a diverging lens will always be on the same side of the lens as the object.

d) It is impossible to combine a diverging lens with a convex spherical mirror in a way that will result in an inverted virtual image

Answer 1

Sol:

a) It is true, because after reflection the rays of light get diverted and do not converge at any point.

b) It is not tru, because if object is placed in between lense and focus point then image is vertual and right up.

c) It is true, because after refraction through lens the rays of light do not converge at any point.

d) It is not true, because inverted image is always inverted and virtual image is always right up.
