Question

Which of the following will undergo maximum diffraction ? 

(A) α – particle (B) γ – rays (C) radio waves (D) light waves

Answer 1

The correct option is (C) radio waves.

Explanation:

Maximum diffraction occurs when size of obstacle is almost equal to wavelength of light wave. Hence maximum diffraction occurs for larger wavelength . As wavelength of radio wave is higher than others, maximum diffraction will occur for it.
