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.
Answer
- It is not necessary that if the rays are diverging after emerging from the lens then the lens is concave.
-
In
Convex lens
, if
object is between O
ptical Center
and F
ocus, the rays are diverging
- If the rays crossing the focal point of the convex lens, become diverging.
- Therefore, lenses can be concave or convex.
Thus,
- Assertion is false
- Reasoning is true
So, the correct answer is (d)
