Question

The ray diagram below shows a case of the image formation by a convex lens. Here the object distance is ____, and the image distance is _____.

  1. Positive, positive
  2. Positive, negative
  3. Negative, positive
  4. Negative, negative

hintHint:

Distances that are calculated in the orientation of the incident ray are positive and the distances calculated  in the direction opposite to the incident rays are negative

The correct answer is: Negative, negative


    • According to the spherical lens, the sign convention is as follows:
    • Distances that are calculated in the orientation of the incident ray are positive and the distances calculated  in the direction opposite to the incident rays are negative.
    • Here both object and image are on the opposite of incident ray so both object distance is Negative____, and the image distance is Negative _
