Q: Most ordinary gases do not show dispersion with visible light. This is because the velocities of propagation of waves of different wavelengths of visible light are ______. (Velocity of light in vacuum is c)
  • A. very much different
  • B. always much less than c
  • C. always much greater than c
  • D. almost the same as c
Correct Answer: Option D - In most ordinary gases, the velocity of propagation of waves of between wavelength of visible light is almost the same as c. Therefore, they do not show dispersion with visible light.
D. In most ordinary gases, the velocity of propagation of waves of between wavelength of visible light is almost the same as c. Therefore, they do not show dispersion with visible light.

Explanations:

In most ordinary gases, the velocity of propagation of waves of between wavelength of visible light is almost the same as c. Therefore, they do not show dispersion with visible light.
