Question

The power of a plano-convex lens is P. If this lens is cut longitudinally along its principal axis into two
equal parts, then the power of the each part is​

Answer 1

Answer:

Same.

Explanation:

When the plano-convex lense is cut longitudinally along the principal axis then the power of the resulting lenses will be same since the focal length does not changes on diving the lense hence the power will also remain the same.

As, we know that if we take the two part of the lenses to have focal length as f1 and f2. Then the resulting lense, 1/f1 + 1/f2 = 1/f which is nothing but p1 + p2 = p. Where the p1 and p2 will be same.

Answer 2

Answer:

P1=P2(1/F1+1/F2=1/F)
