Question

Phenomenon behind the formation of rainbow ?

• A. Diffraction of light
• B. Scattering of light
• C. Interference of light
• D. Dispersion of light

Answer 1

Answer:

D. Dispersion of light

Dispersion is defined as the separation of white light into different colours when the light is passed through the prism.

The scattering of light depends on the wavelength of the light.

Therefore, it can be said that the degrees of deviation is dependent on the wavelengths.

The deviation in the path of the light is inversely proportional to the wavelength.
