# What frequency of sound travels in air at 20 degree C has a wavelength equal to 1.7m?

## Question:

What frequency of sound travels in air at 20 degree C has a wavelength equal to 1.7m?

## The Wave Velocity Formula:

The velocity of the wave indicates how fast the wave is moving between two positions. For longitudinal wave, a number of cycles performed by the wave per second is called a frequency of the given wave. The distance between any successive rarefaction or compression is called a wavelength of the wave. For the constant-frequency wave, the wavelength of the wave is directly proportional to the wave velocity.
