WAVES

TRANSVERSE WAVE

• Crest top of wave
• Trough bottom of wave
• Waves that move the medium in a right angle to the direction in which the wave travels

LONGITUDINAL WAVE

• Move the medium parallel to the direction in which the wave travels
• Compressions are bunched up
• Rarefactions are stretched out

AMPLITUDE

• The maximum distance the medium particles move a wave from its rest position

WAVELENGTH

• The distance between two corresponding parts of a wave

FREQUENCY

• The number of waves that pass a given point and time

HERTZ

• The units that frequency is measured

SPEED

• Is how far a wave in a given length of time

REFLECTION

• When an object or wave hits a surface through which it cannot pass, it bounces back

REFRACTION

• The bending of waves due to change in speed

DIFFRACTION

• When a wave moves through or around a barrier, it bends and spreads out

INTERFERENCE

• The interaction between waves that meet

STANDING WAVES

• If an incoming and reflected wave have the right frequency it makes a combined wave
