Consider the following statements.

1. Ability of the lens to converge or diverge light rays depend upon its focal length.
2. A concave lens of very short focal length causes less divergence than a very long focal length concave lens.

Select the correct statement using the codes given below.
a) 1 only
b) 2 only
c) Both 1 and 2
d) None of the above


Answer - a

Explanation- Statement 1 is obvious fact and correct.Statement 2 is wrong. A concave lens of very short focal length causes more divergence than a very long focal length concave lens by diverging light rays away from the optical centre.
