November 18, Electromagnetic Radiation Objectives At the end of class, you will be able to: List the forms of electromagnetic radiation Find wavelength.

Wavelength The distance between one point on a wave and another point exactly like it.

Light is an electromagnetic wave. Visible light is only a small section of the electromagnetic spectrum. The electromagnetic spectrum stretches from radio.

Waves can also be reflective and refractive Waves can bounce off of something after striking it. That is a reflection. Sound and light waves can equally.
