Vedclass · Answer

(D) The audible frequency range for a human ear is $20 	ext{ Hz}$ to $20,000 	ext{ Hz}$.Taking the speed of sound in air at room temperature as $v \approx 340 	ext{ m/s}$.The wavelength $\lambda$ is given by the formula $\lambda = \frac{v}{f}$.To find the minimum wavelength $\lambda_{\min}$,we use the maximum frequency $f_{\max} = 20,000 	ext{ Hz}$.$\lambda_{\min} = \frac{340}{20,000} 	ext{ m} = 0.017 	ext{ m} = 17 	ext{ mm}$.Rounding to the nearest provided option,the value is approximately $20 	ext{ mm}$.
