In Young's double slit experiment how many maximas can be obtained on a screen (including the central maximum) on both sides of the central fringe it `lambda= 2000A^(0)" and "d= 7000A^(0)`.

Explanation

To determine the number of maxima in Young's double-slit experiment, including the central maximum, we can follow these steps:

### Step 1: Understand the formula for maxima
In Young's double-slit experiment, the condition for maxima is given by:
\[ d \sin \theta = n \lambda \]
where:
- \( d \) = distance between the slits
- \( \lambda \) = wavelength of light
