The Young"s double slit experiment is performed with blue light and green light of wavelengths 4360 Ao and 5460 Ao respectively. If y is the distance of 4th maximum from the central one, then
Given,
Wavelength of blue light, λb=4360 Ao
Wavelength of green light, λg=5460 Ao
Center distance of fourth bright fringe y4th=nλDd,
So, for constant D & d, y α λ
As we know, λb<λg ,
therefore yb<yg
