Question

Why do plane mirrors and convex mirrors form only virtual images?
A. because the focal point is in front of the mirror
B. because they cannot make light rays converge
C. because they only reflect light
D. because they both show a wide angle of view

2 Answer

  • B. because they cannot make light rays converge
  • Answer:

    B. because they cannot make light rays converge

    Explanation:

    When parallel beam of light incident of the plane mirror or convex mirror then light rays are reflected by the surface of mirror in such a way that it will not meet at any point of after the reflection.

    So here the converging point of light rays are virtual point and hence we will say that its focal length is virtual focal length.

    So here correct answer would be

    B. because they cannot make light rays converge
