Question

Consider the following statements A and B :
A) A plano-convex lens behaves as convergent lens irrespective of radius of curvature of convex surface
B) The focal length of a glass plate is zero

• A. A is true and B is false
• B. A is false and B is true
• C. A and B are true
• D. A and B are false

Answer 1

The correct option is A A is true and B is false

A Plano convex lens behaves as convergent lens because has one sided lens which converges the incident rays. The focal length of a glass plate is infinity not zero.hence correct option is A.
