A remote control for a television works by sending out electromagnetic waves. Which is the best description for the behavior of the waves?
The speed of the waves changes as it moves through the air, so the waves refract and diffract.
The remote control sends out longitudinal waves, which then echo off the television detector.
Transverse waves from the remote transmit through air, which are then absorbed by the television detector.
