Two light rays having the same wavelength 
in vacuum are in phase initially. Then the first ray travel a path 
through a medium of refractive index 
, while the travel second ray travels a path of length 
through a medium of refractive index 
. The two waves are then combined to observe interference. The phase difference the two waves is
a)
b)
c)
d)
