Answer:
∅=
Explanation:
z=impedance
=2R
R=R
The resultant of the resistances in the circuit is called impedance
is inductive reactance of the circuit
R is the resistance of the resistor
z=
z=
Z=
Z=Rohms
tan∅=2R/R
tan∅=2
∅=Tan^-1(2)
∅=
phase angle is ∅=
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
