Review Sheet for Wave Phenomena

point source	wavefront
circular wave	plane wave
incident wavefront	incident ray
interface	angle of incidence
normal	angle of reflection
reflected ray	reflected wavefront
image source (circular reflections off a straight barrier)	wavelength (l)
frequency (Ś)	wave velocity (v_w)
relationship between frequency and period (Ś,T)	superposition
interference (resultant)	troughs
crests	destructive (nodes)
constructive (antinodes)	central maximum
changes that occur when two in-phase point sources (same distance apart) change frequency	changes that occur when two in-phase point sources (same f) move closer together vs farther apart
damped	parabolic barrier
focus	relationship between frequency and wavelength (Ś,l)
diffraction	behavior through large vs small openings
behavior around large vs small obstacles	refraction
medium	short wavelengths vs long wavelengths
angle of refraction	bending towards/away from the normal
