उत्तर २

A light ray is incident on a convex mirror parallel to the principal axis. The ray diagram is shown below.

In the above diagram, ‘i’ is the angle of incidence, ‘r’ is the angle of reflection, 'F' is the Focus, 'C' is the Centre of Curvature and 'P' is the Pole.

A student has focused the image of a candle flame on a white screen using a concave mirror. The situation is as given below:

Length of the flame = 1.5 cm

Focal length of the mirror = 12 cm

Distance of flame from the mirror = 18 cm

If the flame is perpendicular to the principal axis of the mirror, then calculate the following:

  1. Distance of the image from the mirror
  2. Length of the image

If the distance between the mirror and the flame is reduced to 10 cm, then what would be observed on the screen? Draw ray diagram to justify your answer for this situation.
