so we will have
now angular frequency is given as
Now the inwards is given as centripetal force
Answer:
540 nm
Explanation:
According to the question,
The refractive index of the soap bubble, .
The thickness of the soap bubble wall is, .
Now, for constructive interference of soap bubble.
.
Now for first order m=1.
Therfore,
Substitute all the variables in the above equation.
.
Therefore,
.
Therefore the visible light wavelength which is strongly reflected is 540 nm.
