Assertion and Reasoning

Assertion: The focal length of an equiconvex lens of radius of curvature R made of material of refractive index μ = 1.5, is R.

Reason: The focal length of the lens will be R/2.

Explanation

- An equiconvex lens is a lens with two convex surfaces of equal curvature. The radius of curvature of each surface is R.
- The refractive index of the lens material is μ = 1.5. This means that light travels 1.5 times slower in the lens material than in vacuum.
- The focal length of a lens is the distance between the lens and the point where light rays from a distant object converge to form a sharp image.
- For an equiconvex lens, the focal length is given by the formula f = R/(2(μ-1)), where μ is the refractive index of the lens material and R is the radius of curvature of each surface.
- Substituting μ = 1.5 in the above formula, we get f = R/2.
- Hence, the Reason is correct as it gives the correct formula for the focal length of an equiconvex lens of radius of curvature R made of material of refractive index μ = 1.5.
- However, the Assertion is incorrect as it states that the focal length is R, which is not true in general. The focal length of an equiconvex lens depends on the refractive index of the lens material, which is not given in the Assertion.

Conclusion

- The correct answer is option 'C', as the Assertion is incorrect but the Reason is correct.
