Question

the power of the convex lens when it is made of material having refractive index (n2=2) and kept in air (n1=1) is equal to​

Answer 1

Answer:

When n1=n2, there is no change in medium.

Solution:

(I) When n1<n2, light goes from rarer to denser medium. Therefore, on passing through a convex lens, it converges,

(ii) When n1=n2, there is no change in medium.
