Question

Diffraction of sound waves is more evident than light waves in daily life because:

• A. ${\lambda }_{\text{sound }}>{\lambda }_{\text{light }}$
• B. ${\lambda }_{\text{sound }}={\lambda }_{\text{light }}$
• C. ${\lambda }_{\text{sound }}<{\lambda }_{\text{light }}$
• D. sound waves are longitudinal but light waves are transverse

Answer 1

Answer: (A)

Diffraction of sound waves is more evident, because wavelength of sound is greater than light.
${\lambda }_{\text{sound }>}{\lambda }_{\text{light }}$
