The refractive index of the material of the prism and liquid are 1.56 and 1.32 respectively. What will be the value of for the following refraction?

Options

  1. A13 11
  2. B11 13
  3. C3 2
  4. D1 2

Correct answer

B. 11 13

Step-by-step solution

Using the formula ( )= _ liquid _ prism = 1.32 1.56 = 11 13 ...(1) Now the condition for total internal reflection, occur when So, 11 13
