Waves were created on three identical ropes. Of the three waves shown, Wave 2 has the greatest ...

• wave speed, because it has more crests than the other ropes.

• frequency, because it has a larger wavelength than the other ropes.

• wave speed, because the rope is moving up and down faster than the other ropes.

• frequency, because there are more crests in the same length of rope than there are in the other waves.

A student has a remote control for a television. The student points the remote at the television and presses a button on the remote labeled Volume. A small red light flashes on the front of the remote. The student observes that the sound from the television becomes lower. Which statement best describes how the remote control communicates

with the television to change the volume of the sound?

• The remote control sends microwaves toward the television that are absorbed by the front of the television.

• The remote control sends low-energy infrared radiation to a light detector on the front of the television.

• The remote control sends radio waves in many directions, which bounce off the walls of the room toward the front of the television.

• The remote control sends sound waves in many directions, which bounce off the walls of the room toward a vibration detector on the front of the television.
