Problem 14-10 Double Slit - C

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. Go back to the problem and carefully decide which numbers belong to the symbols \(x, N\) and \(L\).

Try again.
