Question

Young's double-slit experiment is carried out by using green, red and blue light using one colour at a time. The fringe widths recorded are β G , β R and β B respectively. Then,, β G > β B > β R, β B > β G > β R, β R > β B > β G, β R > β G > β B

MARKS App · Accepted Answer

We know that fringe width is given by β = λD d ∵ λ R > λ G > λ B ∴ β R > β G > β B
