Question

Mention the intensity at central maxima and young double slit experiment is 50 find intensity at a point where path difference is named by 6 and lambda by 4 and lambda by 3

Answer 1

I=4I0cos2(∅2)∅= phase difference∅=2πλ∆x∆x=path differenceI=4I0cos2(∅2)I=4I0cos2(2πλ∆x2)I=4I0cos2(πλ∆x)1.I=4I0cos2(πλλ6)I=4I0cos2(π6)=3I02.I=4I0cos2(πλλ4)I=4I0cos2(π4)=2I03. I=4I0cos2(πλλ3)I=4I0cos2(π3)=I0
