1. 1 2 3 Waves A wave transfers energy
There are three types of waves: transverse, longitudinal, and electromagnetic. 2
Only electromagnetic waves can move through space. 3

2. Transverse Waves
Particles move perpendicular (up and down) compared to the direction of the wave.

3. Waves More energy = more amplitude.
As wavelength decreases, frequency increases.
Speed depends on the material it travels through.
A higher frequency indicates a faster vibration by an
object, a lower frequency indicates
a slower vibration.

4. Particles move back and forth, creating compressions and rarefactions.
Longitudinal Wave
Particles move back and forth, creating compressions and rarefactions.

5. Bouncy Bouncy waves Absorption is when energy is transferred from a
wave to its medium.
Transmission is the passage of light through an object.
During reflection, waves bounce of a surface. The angle of incidence is equal to angle of reflection. If there are many surfaces there will be many angles, and a messed up reflection.
If a wave changes speed, refraction will happen (a bending in the wave).

6. Interference
If crests overlap, a new wave with a higher amplitude is formed. This is constructive interference.
Diffraction affect sound waves like refraction. The waves can bend around corners.
