A lens acts as converging in air and diverging when immersed in water. Then, refractive index of lens is :

Options

  1. Aequal to unity
  2. Bbelow 1.33
  3. Cgreater than 1.33
  4. Dless than unity

Correct answer

B. below 1.33

Step-by-step solution

When lens is immersed in water then its nature changes. The refractive index of lens is less than that of wateri.e., less than 1.33 .
