As it is the concept of youngs experiment so by following the given information and by looking at the diagram we can make out the following equation.
Tan(theta)= Y/D here y is the height at. Which image is formed and D is the distance between the slit and screen.
So at maxima the value will be y=m lamba D/d here small d is the distance between the slit so
The eq is
d sin (theta) = m (L) here as the angle is small so tan thetha= sin theta= theta.
b) applying the formula with values
d= m*685/ sin (4.75)
m*685/0.082
d = 0.83 m millimetres
