Velocity of sound in air does not change with the change of (a)Temperature of air (b)Pressure of air (c)Moisture content in air (d)Wind in the direction of propagation of sound
option B. Air strain has no impact in any respect in a perfect fueloline approximation. This is due to the fact strain and density each make a contribution to sound speed equally, and in an excellent fueloline the 2 results cancel out, leaving simplest the impact of temperature. Sound normally travels greater slowly with more altitude, because of decreased temperature.
