Question

If velocity of sound in air is 340 m/s calculate the frequency of a wave whose wave length is 1m . Will it be audible to us

Answer 1

Frequency of sound wave is 340 Hz. This frequency is in audible range.

Explanation:

The relationship between frequency and wavelength is inverse. The higher the frequency, the shorter the wavelength of a sound wave. The speed of sound can change when sound travels from one medium to another. since, the higher the speed of a sound, the greater its wavelength for a given frequency.

Velocity of sound = 340 m/s

    wavelength = 1 m

   frequency  = ?

    as we know ;

    velocity = wavelength x frequency

      340 = 1 x frequency

Frequency = 340 /1 = 340 hz

this value of frequency  is in audible range.
