Types of Waves
2 main classifications of waves
Mechanical and Electromagnetic
type of wave that sound is
longitudinal
particle of light
photon
True or False - Electromagnetic waves do NOT need a medium to travel.
True
top of a wave
crest
3 types of mechanical waves
Transverse, Longitudinal, Surface
property that affects loudness
amplitude
reflection
part of the electromagnetic spectrum that allows doctors to see bones
x-ray
one crest to the next crest
wavelength
Difference between mechanical and electromagnetic
mechanical waves need a medium
acceptable volume for a human
80 db
State Snell's Law
angle of incidence = angle of reflection
longest wavelength in the electromagnetic spectrum
radio
How to find speed of wave
multiple frequency by wavelength
type of wave in which energy is perpendicular to motion of wave
transverse
Greater frequency = higher pitch
Process that explains rainbows and sunsets
diffraction
State all the parts of the electromagnetic spectrum in order
Radio, microwave, infrared, roygbiv, uv, x-ray, gamma rays
As wavelength increases, frequency ____
decreases
definition of a wave
displacement of energy
echolocation
Why does a straw look bent in a glass of water?
Refraction - speed of light in air is different from speed of light in water
Scientist who discovered infrared
Herschel
height of a wave
amplitude
