A wave of wavelength 0.60 cm is produced in air and it travels at a speed of 300 ms^-1 What will be the frequency of the wave ?

Concept:

Wavelength (λ) is equal to the distance travelled by the wave during the time in which anyone particle of the medium completes one vibration about its mean position. It is the length of one wave.

Frequency (f) of vibration of a particle is defined as the number of vibrations completed by the particle in one second. It is the number of complete wavelengths traversed by the wave in one second.

The relation between velocity, frequency, and wavelength 

c = f × λ

Calculation:

Given:

λ = 0.6 cm = 0.006 m, c = 300 ms-1 

c = f × λ

300 = f × 0.006

f = 50000 Hz

f = 50 kHz
