3. Kinds of Radiant Energy Infrared RaysRadio Waves Ultraviolet raysX-rays

11. A simple model of a light wave begins with a ray (a straight line) that shows the direction of the light’s travel. Perpendicular (at right angles), short arrows represent the electric field.

14. Light is a transverse wave, meaning that the vibrations are perpendicular to the motion and speed of the wave.

15. Electromagnetic Waves Because light consists of electric and magnetic fields, it is called an electromagnetic wave. The term light commonly refers to just those electromagnetic waves that we can see. For light to be visible, it must have a wavelength within a certain narrow range of values called the visible spectrum.

16. Violet Light- has the shortest wavelength that is visible. Red Light- has the longest wavelength that is visible.
