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

A person can hear frequencies only upto 10kHz. A steel piano pipe wire 50cm long of mass 5g is streched with a tension of 400N. The number of the hightest overtone of the sound produced by this plano wire that the person can hear is

A road passes at some distance from a standing man. A truck is coming on the road with some acceleration. The truck driver blows a whistle of frequency 500 Hz when the line joining the truck and the man makes an angle theta with the road. The man hears a note having a note having a frequency of 600 Hz when the truck is closest to him. Also the speed of truck has git doubled during this time. Find the value of 'theta' .

The average range of frequencies at which human beings can hear sound waves varies from 20 Hz to 20 kHz. Calculate the wavelength of the sound wave in these limits . (Assume the speed of sound to be 340 ms^(-1)
