Waves in Different Media

When a wave meets a boundary between two media, it will

• disappear.

• change directions.

• keep going in a straight line.

• cause the particles of the medium to scatter.

Which of these describes the behavior of waves that reflect when they meet a boundary between two media?

• The wave scatters in all directions.

• The wave bounces back and changes direction.

• The wave is pushed back in the exact opposite direction.

• The wave pushes through the media in the same direction.

Transmission describes what happens when

• two waves collide in the same medium.

• a wave splits into two waves within the same medium.

• multiple waves exchange energy within a single medium.

• a wave passes into a new medium and travels through that medium.

How does a sound wave behave when traveling through a concrete wall?

• The wave speed does not change as it travels through the wall.

• The wave slows down as it travels through the wall, and speeds up on the other side.

• The wave speeds up as it travels through the wall, and slows down on the other side.

• The wave speed will change depending on which side of the wall the wave is coming from.

What determines how much of a wave is reflected or transmitted when it meets a new medium?

• The speed of the wave

• The amplitude of a wave

• The wavelength of a wave

• The properties of the two media

Refraction is the bending of a wave

• when the amplitude of the wave suddenly changes.

• when it changes direction while passing through a single medium.

• when it changes speed while passing from one medium to another.

• when it divides into different directions when passing through a new medium.

Under what circumstance would a wave NOT bend when meeting a new medium?

• A wave does not bend when it is passing between similar media.

• A wave does not bend when it is passing from a solid medium to a liquid medium.

• A wave does not bend when it is passing from a liquid medium to a solid medium.

• A wave does not bend when its direction is perpendicular to the boundary between media.

How much a wave refracts depends in part on

• the angle of the wave.

• the energy of the wave.

• the amplitude of the wave.

• the shape of the wave.
