In YDSE, the two slits are separated by 0 . 1 m m and they are 0.5 m from the screen . The wavelengh of light used is ` 5000 Å` . What is the di stance between `7^(th)` minima on screen ?

Explanation

To find the distance between the 7th minima on the screen in Young's Double Slit Experiment (YDSE), we can use the formula for the position of minima in a double-slit interference pattern. The formula for the position of the m-th minima is given by:

\[ y_m = \frac{(m + \frac{1}{2}) \lambda D}{d} \]

Where:
- \( y_m \) = position of the m-th minima on the screen
- \( m \) = order of the minima (in this case, \( m = 7 \))
- \( \lambda \) = wavelength of the light used
