Solved: An interference pattern is produced by four
Chapter 36, Problem 25E(choose chapter or problem)
An interference pattern is produced by four parallel and equally spaced, narrow slits. By drawing appropriate phasor diagrams, show that there is an interference minimum when the phase difference \(\phi\) from adjacent slits is \(\text { (a) } \pi / 2 \text {; (b) } \pi \text {; (c) } 3 \pi / 2\). In each case, for which pairs of slits is there totally destructive interference?

QUESTION:
An interference pattern is produced by four parallel and equally spaced, narrow slits. By drawing appropriate phasor diagrams, show that there is an interference minimum when the phase difference \(\phi\) from adjacent slits is \(\text { (a) } \pi / 2 \text {; (b) } \pi \text {; (c) } 3 \pi / 2\). In each case, for which pairs of slits is there totally destructive interference?
ANSWER:Step 1 of 4
There is destructive interference between the light through slits 1 and 3 and between 2 and 4
