What are the 2 wave types
transverse and longitudinal
What type of wave propogates perpendicular to the motion of the medium
transverse
What type of waves don't need a medium to travel
electromagnetic
What remains constant during refraction
frequency
What is the change in frequency on sound waves caused by a moving source called
doppler effect
What causes radio and microwaves
creation of a circuit/acceleration of e's through a circuit
What are Standing Waves?
wave no chair
What are the Properties of Waves? (4-5)
Amplitude, Wavelength, Period, Frequency and Speed.
Cause of IR,UV,Visible Light
e goes to a lower energy state
Cause of X-ray/Gamma ray
radioactive decay
What's AM
Amplitude Modulation
What's FM
Frequency Modulation
Sound is faster in
denser media/solid
Light is faster in
vacuum
Shortest wavelength light
violet/blue
Energy and Matter display what properties
particle and wave
Wave intensity is proportional to
amplitude
Formula for bright line spectra
m(lamda)=dsin(theta)
Dark line formula
(m+-0.5)(lamda)=dsin(theta)
The refraction law thing
nsin(theta)=nsin(theta)
