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.
$\lambda_{\text {sound }>} \lambda_{\text {light }}$
