The material or substance that a wave moves through is called a <u>MEDIUM</u>. The medium affects the speed of the wave that passes through it. One factor that affects the speed of a wave is the <u>TYPE</u>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 <u>TEMPERATURE</u>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
The Sun's position has a great impact on how much light reaches the surface. Such as at noon, the Sun has the least amount of gas light has to pass through. Meanwhile at dawn/dusk, it has a thicker layer of gas the light has to puncture.
