Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion (A): If the rays are diverging after emerging from a lens; the lens must be concave.
Reason (R): The ST lens can give diverging rays.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.

Assertion and Reasoning

Explanation:

Assertion (A) states that if the rays are diverging after emerging from a lens, the lens must be concave. Reasoning (R) states that the ST lens can give diverging rays.

Option D is the correct answer as assertion (A) is false but reason (R) is true. The reason for this is that a convex lens can also give diverging rays, not just a concave lens. The type of lens (concave or convex) depends on the position of the object with respect to the lens. If the object is closer to the lens than its focal length, a convex lens will give a diverging image.

Therefore, we cannot conclude that the lens must be concave if the rays are diverging after emerging from it. The type of lens depends on various factors such as the position of the object, the focal length of the lens, and the distance between the object and the lens.

In conclusion, while assertion (A) is false, reasoning (R) is true as a ST (short sighted) lens can indeed give diverging rays.
