A light passing through air has wavelength 6000 Å . The wavelength when same ray passes through a glass slab of refractive index 1.5 will be :

Options

  1. A2000 Å
  2. B4000 Å
  3. C8000 Å
  4. D1200 Å

Correct answer

B. 4000 Å

Step-by-step solution

When light ray passes through a glass slab, then new wavelength aligned ^ & = = 6000 1.5 & =4000 Å aligned
