1
Q
define Amplitude A
A
the maximum value of a wave the distance between crest and zero
2
Q
define phase of a wave phi
A
distance between waves. this is a consequence of the starting point of the wave
3
Q
define interference
A
a process in which two or more coherent waves combine to form a resultant wave
4
Q
what is the phase separator for constructive interference
A
zero or an integer
5
Q
what is the phase separation for destructive interference
A
lamda/2 or a multiple
