Answer:
thinnest soap film is 206.76 nm
Explanation:
Given data
wavelength = 550 nm
index of refraction n = 1.33
to find out
What is the thinnest soap film
solution
we have wavelength λ = 550 nm
that is λ = 550 ×
m
and n = 1.3
we will find the thickness of soap film as given by formula that is
thickness = λ/2n
thickness = 550 ×
/ 2(1.33)
thickness = 206.76 ×
m
thinnest soap film is 206.76 nm
The answer is C..........
The answer is d because you have to make sure that everything is right
