Answer:
The possible thickness of the soap bubble = 
Explanation:
<u>Given:</u>
- Refractive index of the soap bubble,

- Wavelength of the light taken,

Let the thickness of the soap bubble be
.
It is given that the soap bubble appears very bright, it means, there is a constructive interference takes place.
For the constructive interference of light through a thin film ( soap bubble), the condition of constructive interference is given as:

where
is the order of constructive interference.
Since the soap bubble is appearing very bright, the order should be 0, as
order interference has maximum intensity.
Thus,

It is the possible thickness of the soap bubble.
It’s not arrested because if you look closer it’s plug walk I don’t even understand how it talk tho
