When white light is incident on a prism, which of the following ray will experience lesser deviation?
- A. Black
- B. Green
- C. violet
- D. Red
Step-by-step solution
White light consists of different colors. The refractive index of the prism material is maximum for violet (shortest wavelength) and minimum for red (longest wavelength). Since deviation increases with refractive index, red light experiences the least deviation.
