Name three forms of energy that travel in waves?
2. Slide

A disturbance that transfers energy from one place to another without transferring matter.
What are Waves?
3. Slide
60 seconds
A wave moves energy from one place to another. A wave moves through matter but does not move it.
How does a wave affect energy and matter?

Mechanical Waves 2. Electromagnetic Wave : a wave that can travel through empty space or through matter.
Two Types of Waves

When a Travels through matter or through empty space.
How are electromagnetic wave formed?

Transverse (Mechanical or Electromagnetic Wave) - moves in a perpendicular (up and down or side to side direction). (Ex.: Flag waving in breeze). High points on a wave are called crests. Low points are called trough. Longitudinal (Mechanical Wave) - a wave that makes the particles of a medium move back and forth parallel to the direction the wave travels. (Ex: sound wave) Combination - both transverse and longitudinal.
Types of Wave Motions

Waves are vibrations that travel through space and have energy. Light waves and sound waves are two types of waves that travel in different ways. We experience light waves as sight and sound waves as hearing.

Waves: a disturbance that transfers energy through a medium, such as air or water. Light: a form of energy that is visible to the human eye and is made up of different colors. Sound: a form of energy that is created by vibrations and is heard by the human ear.

Which type of wave do you think is the most interesting: sound waves, light waves, or both?
• Sound Waves
• Light Waves
• Both

Waves, light, and sound can all be used to measure distances. For example, light waves can be used to measure the distances between planets. The speed of sound is actually faster in cooler temperatures than warmer temperatures. The speed of light is 299,792,458 meters per second, which is the fastest speed in the universe!
