Calculate the minimum thickness of a soap bubble film `(mu=1.33)`that results in constructive interference in the reflected light if the film is illuminated with light whose wavelength in free space is `lambda=600nm`.

Explanation

To calculate the minimum thickness of a soap bubble film that results in constructive interference in the reflected light, we can follow these steps:

### Step 1: Understand the condition for constructive interference
For constructive interference in a thin film, the condition is given by the formula:
\[ 2 \mu t = (n - \frac{1}{2}) \lambda \]
where:
- \( \mu \) is the refractive index of the film,
- \( t \) is the thickness of the film,
