The term dispersion describe the process of (1) reflecting light from a smooth surface (2) the process by which light is absorbed by an uneven rough surface (3) light scattering (4) separating light into its component frequencies Correct Answer 4

Dispersion of Light:

  • Dispersion of light is the splitting of white light into its constituent colors due to the refractive index of the surface and the wavelength of the light.
  • The index of refraction for each color is unique in non-vacuous materials. These unique indices cause each wavelength to follow a different path.

  • If the light entering the prism is not of a single color then the emergent beam also has different colors arranged in a definite order.
  •  It is because the light of different colors has different speeds in a medium except for air.

Important Note: The speed of light decreases a transparent medium with the decrease in the wavelength of light.

The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.
