Question

The product of frequency and wavelength of a sound wave is equal to its

Answer 1

wave length =speed /frequency
then speed =frequency ×wavelength

Answer 2

Sound, similar to all waves, goes at a specific speed and has the properties of frequency and wavelength.

You can watch coordinate proof of the speed of sound while viewing a fireworks display.

The glimmer of a blast is seen a long time before its sound is heard, suggesting both that sound goes at a limited speed and that it is much slower than light.

You can likewise straightforwardly sense the frequency of a sound.

Perception of frequency is called pitch.

The wavelength of sound isn't specifically detected, yet backhanded proof is found in the relationship of the span of melodic instruments with their pitch.
