Behaviors of Waves

Which statement correctly identifies how the energy is used in the device to produce electricity?

• Distance between ocean waves causes gaps in spinning of turbine, which allows production of electrical energy inside the generator.

• Speed of ocean waves causes turbine to rotate, which continually produces electrical energy inside the generator.

• Amplitude of ocean waves determines how much air column rises the rotates the turbine, which produces electrical energy inside the generator.

• Frequency of ocean waves determines how high air column rises that rotates the turbine, which produces electrical energy inside the generator.

A speaker produces a sound wave that is directed toward an object. The image shows what happens to the sound wave once it touches the object.

What is true about the sound wave?

• The sound wave is reflected by the object, causing an echo.

• The sound wave is refracted by the object, changing the wave’s direction.

• The sound wave is absorbed by the object, increasing the wave’s volume.

• The sound wave is transmitted by the object, reducing the volume of the sound.

A beam of light is directed toward two different materials, A and B. The image shows how the beam’s light waves interact with the materials.

What can be concluded about materials A and B?

• Materials A and B are transparent.

• Materials A and B are translucent.

• Material A is transparent, and material B is opaque.

• Material A is translucent, and material B is transparent.
