Two slits `4.0 xx 10^(-6)` m apart are illuminated by light of wavelength 600nm . What is the highest order fringe in the interference pattern?

Explanation

To find the highest order fringe in the interference pattern created by two slits, we can follow these steps:

### Step 1: Understand the relationship between path difference and order of fringes
The path difference (Δx) for constructive interference is given by the formula:
\[ \Delta x = n \lambda \]
where \( n \) is the order of the fringe and \( \lambda \) is the wavelength of the light.
