Which of the following equations describes the condition for observing the fourth bright fringe in Young's doubleslit interference pattern? Assume n = 0 for the central bright fringe.
Which of the following equations describe the condition for observing the fourth dark fringe in an interference pattern correctly?
d sinè = ë
d sinè = 3ë/2
d sinè = 3ë
d sinè = 4ë
I was going to say d sinè = 4ë for dark fringe, but then i don't know what it is for bright fringe.
