In which of the following, the image of an object placed at infinity will be highly diminished and point sized?

(a) Concave mirror only

(b) Convex mirror only

(c) Convex lens only

(d) Concave mirror, convex mirror, concave lens and convex lens

 

Answer

A convex lens makes parallel rays converge onto a single point (the focus)

  • A concave mirror converges  parallel beams of light at the focus to form a highly diminished, point sized image.
  •  A convex mirror diverges parallel beams of light such that they appear to come from the focus. This produces a highly diminished, point sized virtual image
  • A convex lens converges  parallel beams of light at the focus to form a highly diminished, point sized  image.
