Energy Transfer Wave Properties 4-PS3-2

Amplitude

The energy in a wave. Amplitude. Amplitude is how tall a wave is, and it shows how strong or loud the wave is.

Electric current

A flow of electric charge, it is measured in amperes A. Electric current. Electric current is like a river of tiny particles called electrons moving through a wire.

Heat

The thermal energy transferred from a warmer object to a cooler object. Heat. Heat is when energy moves from something hot to something cool, warming it up.

Light

Electromagnetic energy that travels in waves, not all light is in the visible spectrum. Light is a type of energy that we can see, which helps us to see the world around us.

Medium

The substance through which a wave can travel, like air, which carries sound waves, is called a medium. A medium is the material or space through which sound moves, like air, water, or a solid object.

Radiation

The transfer of energy by electromagnetic waves, it does not require matter. Radiation. Radiation is energy that travels through space or air as invisible waves, like sunlight.

Transverse wave

A wave that moves particles of matter at right angles to its direction of travel. Transverse wave. A transverse wave is like the up-and-down motion of a rope when you shake one end.
