Complete the passage to summarize factors affecting the speed of a wave. 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.

The material or substance that a wave moves through is called a medium. It is also known as wave medium, which describes a pathway to carry a wave or disturbance from its source to other locations.

Moreover, 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. The highly rigid medium has higher density, where the speed of sound wave is maximum.

While in the lower density medium, the speed of sound wave is lesser. Because of this, the sound travels faster in solid, than air and water.

Another factor that affects wave speed is the temperature of the medium. Higher the temperature, more will the molecular vibration and more will be the intermolecular spaces. This causes sound to travel more faster. So, increasing the temperature causes the increment in the speed of sound.

Thus, we can conclude that the missing words from each paragraph are medium, type and temperature respectively.
