NEET Physics Question - Ray Optics - Lens Makers Formula/ Len's Formula

Assertion (A): Biconvex lens can form virtual image of a virtual object.

Reason (R): Nature of lens depends on refractive index of surrounding.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

A biconvex lens can form a virtual image of a virtual object, for instance, when intercepting converging rays. So (A) is true. The nature of a lens (converging or diverging) is determined by the refractive index of its material relative to the surrounding medium. If \(\mu_{lens} > \mu_{medium}\), a biconvex lens converges; otherwise, it diverges. So (R) is true and explains (A).
