Question

Diffraction effects are easier to notice in the case of sound waves than in the case of light waves because(a) Sound waves are longitudinal(b) Sound is perceived by the ear(c) Sound waves are mechanical waves(d) Sound waves are of longer wavelength

Answer 1

Option c.sound waves are mechanical waves.

Answer 2

Answer:

Diffraction effects are easier to notice in the case of sound waves than in the case of light waves because (d) Sound waves are of longer wavelength.

Explanation:

Sound waves are larger and also longitudinal, their diffraction is more pronounced. Coherence is also a property of longer wavelengths and thereby easier to detect its diffraction pattern.
