Which describes the amplitude of a wave?

A wave has a height of 5 meters.

A wave has a frequency of 5 hertz.

A wave takes 5 minutes to pass a point.

What is true of all transverse waves and longitudinal waves?

They must travel through a medium.

They can travel through empty space.

They move particles from one place to another.

A mechanical wave is traveling through medium A. When the wave enters medium B, it speeds up. Which of these statements could be true about medium A and medium B?

Medium A is a liquid and medium B is a solid.

Medium A is a solid and medium B is a gas.

Medium A is a gas and medium B is a vacuum.

Medium A is a vacuum and medium B is a liquid.

What happens when a mechanical wave encounters a boundary between two different media? Choose all the true statements.

Some of the wave can be transmitted into the new medium.

Some of the wave is reflected back into the original medium.

The wave is completely reflected.

The wave is completely transmitted.

When a mechanical wave is partially reflected and partially transmitted, it becomes two waves. What happens to the energies and amplitudes of the two waves? Choose all the true statements.

Each of the new waves will have less energy than the original wave.

Each of the new waves amplitudes could be very different.

Each of the new waves will have more energy than the original wave.

Each of the new waves amplitudes will definitely be the same.

Why are earthquakes more intense near the initial disturbance than they are farther away? Choose all the true statements.

The amplitude of the mechanical wave is greatest near the initial disturbance.

The amplitude decreases and the wave's energy is absorbed by Earth.

The amplitude of the mechanical waves is least near the initial disturbance.

The amplitude increases and the wave's energy is absorbed by Earth.

Which statement best describes how the particles of a medium behave when a mechanical wave moves through the medium?

Particles move as the wave passes them but do not move along with the wave.

Particles travel in the direction of the wave, away from the source of the wave.

Particles in the medium travel in the direction that is perpendicular to the motion of the wave.

Particles stay in one place as the wave travels past them.

How are light waves different from sound waves?

Sound waves require a medium to travel through. Light waves can travel through a vacuum.

Light waves require a medium to travel through. Sound waves can travel through a vacuum.
