Section 1



**//__Types of Waves__//** // __Mechanical Waves__- A wave to requires a medium through which to travel. A mechanical wave requires a medium. It is made up of longitudinal // and transverse. Longitudinal can travel through a solid, liquid and gas. An example of longitudinal is a sound wave. Transverse can travel through liquid and gas. An example is rope or water.

__Electromagnetic Waves__- a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light. Electromagnetic waves do not require a medium. It is transverse. //An example of transverse is light waves and radio waves.//

Key terms
 * wave- a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium.
 * medium- a physical environment in which phenomena occur.
 * Transverse Wave- a wave in which the particles of the medium move perpendicular to the direction of the wave is traveling.
 * longitudinal Wave- a wave in which the particles of the medium vibrate parallel to the direction of wave motion.

Section 2 ====== The crust is the high point on a wave and the trough is the lowest part the wave. The wavelength is from one crest to the next crest .The amplitude is from the center to the very top of the crest part of the wave.

Waves


 * When waves are moving though a medium of through space they move in straight lines.
 * Constructive Interference- any interference in which waves combine so that the resulting wave is bigger than the original waves.
 * Destructive Interference- any interference in which waves combine so that the resulting wave is smaller than the largest of the original waves.[[image:waves70:waveinterference.gif caption="waveinterference.gif"]]
 * Reflection- the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through.
 * Diffraction- a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening.
 * Refraction- the bending of a wavefront as the wavefront passes between two substances in which the speed of the wave differs
 * Interference- the combination of two or more waves of the same frequency that results in a single wave.
 * Standing Wave- a pattern of vibration that simulates a wave that is standing still.
