The material or substance that a wave moves through is called a . the medium affects the speed of the wave that passes through it. one factor that affects the speed of a wave is the of medium. some waves move faster in solids and some waves move faster in liquids and gases. another factor that affects wave speed is the of the medium.

A wave can regarded as the disturbance, it can move through a medium and there are different medium for propagation

The speed of wave can be affected by temperature and some wave moves faster in solids and some waves move faster in liquids .

The material or substance that a wave moves through is called a MEDIUM. The medium affects the speed of the wave that passes through it. One factor that affects the speed of a wave is the TYPE of medium. Some waves move faster in solids and some waves move faster in liquids and gases. Another factor that affects wave speed is the TEMPERATURE of the medium.

Explanation:

As we know that the speed of the wave is given as

here we know that

E = elasticity of the medium

= density of the medium

So here we know that speed of the wave will change with the elasticity of the medium which meas it is the type of medium on which the speed of wave will depends upon.

Another we can say for liquid or gas we can say that

so speed will depends on the temperature of the medium

so here answers are

1)Medium

2)Type of medium,

3)Temperature

explanation:

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
