Amplitude

________- distance from center to crest trough.

Microwaves

________- easily absorbed by water (radar, cell phone)

Gamma

________ rays- generated from nuclear reactions (stars, bombs)

wavelength

Parts of a wave that is measurable: ________, amplitude, wave speed, period, and frequency.

Waves

________- repeated motion /vibrations that travel through a medium.

Medium

________- material the wave travels through.

Light waves

________- don't require a medium, travels fastest in a vacuum.

X rays

________- imaging bones, radiotherapy.

Visible Light

________- only part of spectrum you see.

Wavelength

lamida

Parts of a wave that is measurable

wavelength, amplitude, wave speed, period, and frequency

Mechanical waves

requires a medium (sound, water)

Radio waves 

emitted by radio stations and stars

Microwaves

easily absorbed by water (radar, cell phone)

Infrared

"below red," associated with heat (night vision, weather forecasting)

Visible Light

only part of spectrum you see

Ultraviolet waves

"beyond violet" (kills viruses, lowers sunburns)

X-rays

imaging bones, radiotherapy

Gamma rays

generated from nuclear reactions (stars, bombs)

Light waves

don't require a medium, travels fastest in a vacuum

Speed of light

3.00x10^8 m/s

Medium

material the wave travels through

Transverse waves

moves perpendicular to the direction of travel

Crest

top of the wave

Trough

bottom of the wave

Amplitude

distance from center to crest or trough

Compress zone

particles close together

Period (T)

time it takes for one length to pass (units = s)

Frequency (F)

number of waves that pass each second

Hertz (Hz)

1 Hz = 1 wave per second

Equation for Wave Speed

Speed = frequency x wavelength

Waves are in phase

amplitudes add together

Superposition

combining of waves

Kilo

x10 to the 3

Mega

x10 to the 6

frequency
