    A man x can hear upto 10 kHz and another man y upto 2 kHz. A note of frequency 500 Hz is produced before them from a stretched string then both will hear sounds of:

    A)  different pitch but same quality

    B)  same pitch but different quality

    C)  same pitch and same quality

    D)  different pitch and different quality.

    Correct Answer: B

    Solution :

    \[{{f}_{0}}=500Hz\] \[f\frac{1}{2l}\sqrt{T/\mu }\] Frequency depends upon tension and length of string pitch \[\propto \]frequency quality \[\propto \] wave form. Here T and\[l\]is same hence f can not be changed \[\therefore \] pitch will be same but wave form will be different because of their hearing capacity.
