Answer #1

Solution:

Given data

The wavelength of the vanadate laser,

The distance between the slits,

(a)

The condition for resulting a maxima is

Here, it is given that m = 1

Now, substitute the known values in the following equation

(b)

The condition for the minima is given by

Here, we have to calculate the angle for second minima i.e. m = 2

Substitute the known values in the equation

A 600 nm laser shines through a double slit in which the two slits are 0.8 mm apart, and each slit is 0.1 mm wide. Sketch what the pattern would look like on a screen 3 m away and indicate the central maximum. How many bright spots lie between the first single-slit minimums on either side? How far away is that first single-slit minimum from the center of the pattern? (you may assume the small angle approximations)
