Mechanical Waves

Which of the following is NOT an example of a mechanical wave?

• Sound waves

• Water waves

• Earthquake waves

• Light waves

How do mechanical waves travel through a medium?

• By heating the medium.

• Through the motion of the medium's particles.

• By changing the chemical composition of the medium.

• Without affecting the medium at all.

What happens when a boat moves through water?

• The boat creates a mechanical wave by heating the water.

• The water molecules move, creating waves in the wake of the boat.

• The boat absorbs the water molecules.

• The water molecules move without creating any waves.

How does the density of a medium affect the speed of sound?

• The higher the density, the slower sound travels.

• The higher the density, the faster sound travels.

• Density has no effect on the speed of sound.

• Sound can’t travel through a dense medium.

What effect does a medium have on the speed of sound?

• It slows down the speed of sound.

• It does not affect the speed of sound.

• It causes the speed of sound to increase.

• It makes the sound disappear.
