Two light rays will interfere constructively with maximum amplitude if the path difference between them is:
a) one wavelength
b) one-half wavelength
c) one-quarter wavelength
d) one-eighth wavelength
Ans:
When the path difference between two light rays is one wave length, these rays will interfere constructively with maximum amplitude.
