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 off 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 control send sound waves in many directions, which bounce of the walls of the room toward the vibration detector on the front of the television
