Answer #1

## In a typical air situation, the speed of the sound is constant.

The speed of sound can be written as

where, P is the pressure and ρ is the density of the gas and we can rewrite the above equation as

where, T is the temperature of the medium. So, at a constant temperature, the speed of sound is constant in air medium.

## Frequency of light is constant in air medium.

The wavelength of light changes and the velocity of light also changes depending on the medium. Only the frequency of light is constant throughout the propagation of light.
