Waves

A person produces a sound wave that is directed towards and object. The image shows what happens to the sound wave once it touches the object. What is true about sound waves?

• The sound wave is absorbed by the object and increases the volume

• The sound wave is refracted by the object and changes the wave's direction

• The sound wave is reflected by the object and causes an echo

• The sound wave is transmitted by the object and reduces the volume

What happens to a wave when it travels through a different medium such as a wave traveling from air to water?

• The speed of the wave changes

• The wave will stop moving

A beam of light is directed towards a material. The wave is absorbed. What can be concluded about the material?

• It is transparent

• It is translucent

• It is opaque

• We cannot conclude anything about the material because we don't have enough information
