Vedclass · Answer

(D) The pitch of a sound is determined by its frequency. Since both men $x$ and $y$ can hear frequencies up to $10 \ kHz$ and $20 \ kHz$ respectively,and the produced frequency is $500 \ Hz$,both are well within their audible range ($20 \ Hz$ to $20 \ kHz$).Since the frequency of the sound is the same $(500 \ Hz)$ for both,the pitch perceived by both will be the same.Quality (or timbre) depends on the waveform of the sound. Since the sound is produced by the same source (a stretched string),the waveform is identical for both observers.Therefore,both will hear sounds of the same pitch and the same quality.

$A$ man $x$ can hear only up to $10 \ kHz$ and another man $y$ up to $20 \ kHz$. $A$ note of frequency $500 \ Hz$ is produced before them from a stretched string. Then:
