Asked by Lovely
Which of the following equations describe the condition for observing the fourth dark fringe in an interference pattern correctly?
d sinθ = λ
d sinθ = 4λ
d sinθ = 5λ/2
d sinθ = 7λ/2
I would think B but I feel like the answer that has a '4' in it (fourth fringe, four... yeah) would be too obvious

d•sinθ=2k•λ/2=k λ
k=4
d•sinθ==4 λ
k=4
d•sinθ==4 λ
