In double slit experiment using light of wavelength `600 nm`, the angular width of a fringe formed on a distant screen is `0.1^(@)`. What is the spacing between the two slits ?

Explanation

To solve the problem of finding the spacing between the two slits in a double slit experiment, we will follow these steps:

### Step 1: Understand the relationship between angular width, wavelength, and slit spacing
In a double slit experiment, the angular width (θ) of the fringe is related to the wavelength (λ) of the light and the spacing between the slits (d) by the formula:
\[ \theta = \frac{\lambda}{d} \]
Where:
