A wave is any disturbance that transfers energy from one point to another through matter
A wave is any disturbance that transfers energy from one point to another through matter
Matter that allows energy to pass through it is called a medium
Matter that allows energy to pass through it is called a medium
The atoms inside a medium DO NOT MOVE POSITION. They only carry the energy to the next atom

Mechanical Waves
Mechanical waves are waves that require mediums to travel
Mechanical waves are waves that require mediums to travel
Examples of mechanical waves are sound, water waves, and slinky waves
Examples of mechanical waves are sound, water waves, and slinky waves
There are two different types of mechanical waves:
There are two different types of mechanical waves:
- Transverse
- Longitudinal (compression)
The matter in transverse waves vibrate up and down perpendicular to the direction of the wave
The matter in transverse waves vibrate up and down perpendicular to the direction of the wave
The matter in longitudinal (compression) waves vibrate forward and backward parallel to the direction of the wave
The matter in longitudinal (compression) waves vibrate forward and backward parallel to the direction of the wave
Transverse and Longitudinal Waves have different parts which help scientists identify them.

Electromagnetic Waves
Electromagnetic Waves
Electromagnetic (EM) waves do not require a medium to travel. This means that EM waves can travel through space

EM waves look like transverse waves.
EM waves look like transverse waves.
EM waves travel in all directions from the source and are made up alternating electric and magnetic fields

Light is an example of an electromagnetic wave and can appear as many different types. We graph the different strengths of light on the electromagnetic spectrum.
