A thin film is illuminated by wavelength 600 nm in free space at nearly normal incidence. Calculate the minimum thickness of a thin film (`mu` = 3/2 ) that results in constructive interference in the reflected light.

Explanation

To solve the problem of finding the minimum thickness of a thin 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:

\[ 2 \mu t = (2n + 1) \frac{\lambda}{2} \]

where:
