Understand that radiant energy refers to energy that travels by waves or particles, particularly electromagnetic waves.
Recall that visible light is a type of electromagnetic radiation, which means it is a form of radiant energy.
Recognize that chemical energy is stored in chemical bonds and is not radiant energy.
Know that sound waves are mechanical waves requiring a medium to travel and are not electromagnetic radiant energy.
Identify mechanical energy as energy associated with motion or position, not a form of radiant energy.
