Answer:
t = 120.5 nm
Explanation:
given,
refractive index of the oil = 1.4
wavelength of the red light = 675 nm
minimum thickness of film = ?
formula used for the constructive interference
where n is the refractive index of oil
t is thickness of film
for minimum thickness
m = 0
t = 120.5 nm
hence, the thickness of the oil is t = 120.5 nm
