The wavelength of a sound wave was measured to be 0.782 m. if you know that the speed of sound in air was 343 m/s, then determine the frequency of the sound wave.

Frequency of the sound wave will be 438.61 Hz

Explanation:

We have given wavelength of the sound wave

Speed of the sound wave v = 343 m/sec

We have to find the frequency of the sound wave

We know that speed of the sound wave is given by , here v is velocity, is wavelength and f is frequency

So frequency f

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
