Question: Draw a picture how the following travel light sound and heat?

Heat can be transferred by radiation conduction and convection. Visible light can be produced reflected refracted and separated into light of various colors. Sound cannot travel through empty space it is carried by vibrations in a material or medium. Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do.
