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.
