Problem 14-10 Double Slit - Part 2 - A
A laser beam with light of wavelength \(638.2\; nm\) is used to check a manufacturer's claim that a double slit has a separation of \(0.200\; mm.\) The distance to the screen is \(3.00\; m\) and the measured distance from the central maximum to the middle of the fourth minimum is \(33.2 \;mm.\) What is the measured slit separation?
[Ans. \(0.202 \;mm\)]
No. \(x/L = M\lambda/d\)
This is the relation for interference maxima.
