Correct Answer - Option 3 : Microwaves

CONCEPT:

Diffraction​​:

  • ​​​It is defined as the bending of waves around the corners of an obstacle​.
  • The condition of diffraction is that the width of the obstacle must be less than or comparable with the wavelength of the wave.
  • Diffraction is the characteristic of all types of waves.
  • The greater the wavelength of the wave higher will be its degree of diffraction.
  • The condition of diffraction is that the width of the obstacle must be less than or comparable with the wavelength of the wave.

EXPLANATION:

Type of Radiation Wavelength Range
Gamma-rays < 10-12 m
Ultraviolet 400 nm – 1 nm
Infrared 25 μm – 2.5 μm
Microwaves 1 mm – 25 μm
  • Diffraction is the characteristic of all types of waves. i.e., the greater the wavelength of the wave higher will be its degree of diffraction.
  • Since the wavelength of the microwaves is maximum, so the microwaves will show maximum diffraction.
  • Hence, option 3 is correct.
