, monochromatic light of wavelength 
is incident normally on a thin film of uniform thickness 
(where 
) and index of refraction 
. The light transmitted by the film travels into a medium with refractive index 
. The value of minimum film thickness when maximum light is transmitted if 
is -

Text Solution
Verified by ExpertsThe correct answer is:
B
Equation of path difference for maxima in transmission (or weak reflection);
(notice that 
wavelength is medium is related to 
as, 
)
