what is the most common type of wave
sinusoidal
wavelength
represented by lambda
-unit/m
-distance between two crests (or troughs) of the wave
frequency
f or v
-Hz or 1/sec
-number of oscillations per unit time
Amplitude
-A or I
-max height or trough of the wave
what are two properties of waves that particles never do
diffraction and interference
diffraction
spread out when transversing a small opening
interference
passes through two slits and has light and dark bends
what is a class of waves (including visible light)
electromagnetic waves (EM)
do electromagnetic waves need a medium to propagate
no
propagation
movement
