The refractive index of the medium is = A + B ² , where A and B are constants and is the wavelength of light. The dimensions of B are same as that of

Options

  1. AVelocitv.
  2. Barea.
  3. Cwavelength.
  4. DVolume.

Correct answer

B. area.

Step-by-step solution

= A + B ² . Equating dimensions give B ² = M ⁰ ~L ⁰ ~T ⁰ B = M ⁰ ~L ² ~T ⁰ same as dimension of area.
