If an equiconvex lens is made of number of layers of different refractive index for a given wavelength as shown in the figure, then number of images formed for an object kept in front is

Options

  1. Aonly 1
  2. B2
  3. C2.5
  4. D5

Correct answer

B. 2

Step-by-step solution

Given materials of ₁ and ₂ refractive indices are used to form lens. So, corresponding to these, there are two focal lengths of lens. Thus, the number of images formed will be 2 .
