Sound waves are also known as ----- waves.

• Compression

• Longitudinal

• Neither

• Both longitudinal and compression

Sound travels SLOWEST through :

• Solids

• Liquids

• Gases

Answer explanation

Just like the dominoes, the molecules in a SOLID are closer together, so sound is able to travel faster.

In a gas, the molecules (dominoes) are farther apart, so sound travels slower.

Based on the graph, what can you conclude about the speed of sound through different mediums?

• Sound travels fast through solids than it does through liquids and gasses

• Sound travels faster through gasses than it does through liquids and solids

• Sound travels fastest through liquids

• Sounds travels fastest through air

What happens when you increase the amplitude of a sound?

• it makes the sound louder

• it makes the sound travel faster

• it increases the wavelength of the sound

• it increases the frequency of the sound
