A sound wave of frequency 660 Hz incidents normally on a perfectly reflecting surface. If the speed of sound in air is `330 m s^(-1)`, what is the time taken by a particle in the medium to complete one vibration? Determine the wave length of the wave.

Text Solution

Verified by Experts

Frequency of the wave (n ) = 660 Hz
Speed of the sound wave `(V) = 330 ms^(-1)`
`:.` Wavelength `(lamda) (V)/(n) = (330)/(660) = (1)/(2) I`
Time period, `T = (1)/(f) = (1)/(660) s`
