STANDARD Physics Refraction through lenses MCQ Question
A double convex lens, made of a material of refractive index μ₁, is placed inside two liquids of refractive indices μ₂ and μ₃ as shown. μ₂ > μ₁ > μ₃. A wide, parallel beam of light is incident on the left. The lens will give rise to
a single convergent beam
two different convergent beams
two different divergent beams
a convergent and a divergent beam.
Correct Answer
Detailed Explanation
As μ₂ > μ₁, the upper half of the lens will become diverging. And μ₁ > μ₃, the lower half of the lens will become converging.
