Question

Assertion (A): If the rays are diverging after emerging from a lens; the lens must be concave.
Reason (R): The convex lens can give diverging rays.


a. A and R both are correct and R is the correct explanation of A

b. A and R both are correct and R is not the correct explanation of A

c. A is true but R is false

d. R is true but A is false

please give answer with full explanation ​

Answer 1

c. A is true but R is false.

Explanation

Concave lens is diverging lens and convex lens is converging lens.

Answer 2

Correct option for rays is -

c. A is true but R is false

There are two types of lenses namely, concave and convex lens.

Concave lens is diverging lens because rays that pass through it diverge.

The characteristics of image produced by concave lens is - virtual, upright and diminished.

Convex lens is converging lens as the rays passing through the lens converge.

The characteristics of the image produced is - real, inverted and diminished for a distant object and magnified for object close to lens.
