Answer:
442.75862 nm
Explanation:
m = Order
n = Refractive index
= Wavelength
We have the relation of thickness and wavelength given by
The consecutive spectral line is given by
So,
and
Dividing the wavelengths we get
The film thickness of oil is 442.75862 nm
Answer:
= 1227.9K
Explanation:
Given that,
D₀ = 4.0 x 10⁻⁵ m²/s,
Qd = 230,000 J/mol,
D = 6.48 x 10⁻¹⁵ m²/s
Gas constant R = 8.31 J/mol-K
T =
=
=
= 1227.93K
≅1227.9K
