Which of the following is TRUE of light and sound waves?
Answer Details
The correct option is: "they both transmit energy". Both light and sound waves are forms of energy that are transmitted through space. Light waves are electromagnetic waves that can travel through a vacuum, while sound waves are mechanical waves that require a medium, such as air, to propagate. Unlike light waves, sound waves are longitudinal waves, meaning that they vibrate in the direction of their motion, whereas light waves are transverse waves, meaning that they vibrate perpendicular to their direction of motion. The velocities of light and sound waves are not equal in air, with light waves traveling much faster than sound waves.
