Question

identify the factors responsible to change the speed and also mention how the factor is related to the speed of sound: A sound wave travels from air to helium gas.

Answer 1

Answer:

Sound travels more slowly than light, and it does not always travel at the same speed. Two main factors affect the speed of sound: the material that makes up the medium—such as air or water—and the temperature. If we know the medium and the temperature, however, we can predict the speed of sound.

The speed of sound depends on the nature of material (or medium) through which it travels. Sound travels faster in liquids than in gases and faster in solids than in liquids. Sound travels about 5 times faster in water than in air.
