Q: When white light is passed through a prism it undergoes dispersion. The angle of deviation is:
  • A. directly proportional to the wavelength
  • B. inversely proportional to the wavelength
  • C. independent of the wavelength
  • D. maximum for red color
Correct Answer: Option B - When white light is passed through a prism it undergoes dispersion. Then the angle of deviation is inversely proportional to the wavelength.
B. When white light is passed through a prism it undergoes dispersion. Then the angle of deviation is inversely proportional to the wavelength.

Explanations:

When white light is passed through a prism it undergoes dispersion. Then the angle of deviation is inversely proportional to the wavelength.
