25 Quiz II

What is a transverse wave?

• A wave where particles of the medium move parallel to the direction of wave propagation.

• A wave where particles of the medium move perpendicular to the direction of wave propagation.

• A wave that does not require a medium to travel.

• A wave that travels faster in a vacuum.

Which of the following is a characteristic of longitudinal waves?

• They can travel through a vacuum.

• They require a medium to propagate.

• They have crests and troughs.

• They are electromagnetic waves.

How does the speed of a mechanical wave change with the medium?

• It remains constant regardless of the medium.

• It increases with the density of the medium.

• It decreases with the density of the medium.

• It depends on the elasticity and density of the medium.

Which of the following is an example of a transverse wave?

• Sound wave

• Light wave

• Seismic P-wave

• Water wave

What is the primary difference in particle motion between transverse and longitudinal waves?

• Transverse waves have particles moving parallel to wave direction, while longitudinal waves have particles moving perpendicular.

• Transverse waves have particles moving perpendicular to wave direction, while longitudinal waves have particles moving parallel.

• Both have particles moving in the same direction as wave propagation.

• Both have particles moving in opposite directions to wave propagation.
