How many types of em waves are there?

7

1

Reflection

The bouncing back of a wave after it strikes a barrier

2

Refraction

The bending of a wave as it enters a new medium

3

Diffraction

The spreading out of a wave through an opening or an obstacle

4

Examples of refraction:

A straw inside a glass of water

5

Example of reflection:

Holding a light to a mirror and having it bounce another way

6

Example of diffraction:

When you can hear sound even though windows, doors, ect.

7

Incandescence

The production of light by materials at high temperatures. (Sun)

8

Luminescence

The production of light without high temperatures. (Glow sticks)

9

Fluorescence

Occurs when a material absorbs EM radiation of one wavelength and gives off EM radiation of another. (Computer)

10

Transmission

The passage of an EM wave through a medium

11

Absorption

A dissaperence of an EM wave into the medium

12

Scattering

The spreading out of light waves in all directions

13
