waves

Frequency

determines pitch

Amplitude

maximum displacement from resting to peak

Wavelength

length of one wave

Crest

highest point

Trough

lowest point

Compression

particles close together

Rarefaction

particles spread apart

Transverse wave

particles move perpendicular to wave

Longitudinal wave

particles move parallel to wave

Resonance

vibration at natural frequency

Doppler Effect

change in pitch due to motion

Sonic Boom

object exceeds speed of sound

Reflection

light bounces off

Refraction

light bends

Absorption

light converted to heat

Transmission

light passes through

Scattering

light spreads in many directions

Photon

particle of light

Infrared

associated with heat

Ultraviolet

can damage skin

Vacuum

no matter present

What determines pitch?

Frequency

Highest point of a wave?

Crest

Bending of light?

Refraction

Light particle?

Photon

snells law

light bends as it passes one medium to another

white light

combo of all light

black light

absence of all colors of light

white pigment

absence of all color

black pigment

combo of all colors

infrasonic

sounds people cant hear

index of refraction

measures how much light slows down and bends when it enters a new material
