Question

If a lens has positive power then a) Light ray passing through it bends towards the normal b) Light ray passing through it bends away the normal c) Light ray does not deviate d) None of these When bolens and divercing lens ofequal focal length are kept in contact​

Answer 1

Answer:

option (a) is the correct answer

Answer 2

Choose the correct option for this given question

Explanation:

• If lens bends or deviates the ray which is passing through towards its center which means it converges the ray, the power becomes positive.
• If the ray passes through lens gets deviate away from perpendicular or center which means lens is diverging the ray, the power becomes negative.

• Hence, power of convex-lens is a positive value & of a concave-lens is a negative.

• Option a is correct-option for this given question.
