Answer»

Answer:

TEMPERATURE

Explanation:

1) Density - therefore density of air is inversely proportional to velocity of sound (at constant temperature)

------> that is the greater the density of air the lower will be the speed of sound

2)Relative Humidity - the speed of sound increases with humidity in air ..therefore speed of sound in wet air or moist air is more than speed of sound in dry air ..

--------> so humidity directly proportional to speed of sound

3) nature of transmitting medium

3) nature of transmitting medium4) Temperature - (in gases)

v ∝√T

i.e. with increase in temperature velocity of sound in a gas increases.

5) Pressure -

Change in pressure has no effect on velocity of sound in a gas, so LONG as temperature remains constant; because ;

P/ρ = constant; as long as temperature is constant.

Note: The speed of sound in air is not affected by Amplitudes, frequency, phase, loudness, PITCH, or quality.
