Two slits are separated by 0.380 mm. a beam of 550-nm light strikes the slits, producing an interference pattern. determine the number of maxima observed in the angular range

total maximum on screen = 1381

Explanation:

In the interference pattern we know that path difference for the position of maximum on the screen is given by

here we know that

= angular position of maximum on screen

d = distance between two slits

here we know that for all maximum positions

now plug in all values

here we have

now we know that

so total number of maximum on screen is
