What happens when a beam of pure white light passes through a prism?
Question

What happens when a beam of pure white light passes through a prism?

A.

The ray will be reflected

B.

The ray will converge

C.

The beam will flicker

D.

The ray will be scattered

Correct option is D

The  Correct Answer is: (d) The ray will be scattered

  • When a beam of pure white light passes through a prism, the light undergoes dispersion, separating into its constituent colors (spectrum) due to the different degrees of refraction experienced by different wavelengths of light.

Information Booster:

  • Dispersion occurs because the refractive index of the prism material varies with wavelength.
  • Violet light, having the shortest wavelength, bends the most, while red light, with the longest wavelength, bends the least.
  • This creates a spectrum of colors, known as VIBGYOR (Violet, Indigo, Blue, Green, Yellow, Orange, Red).
