Lexy and jin study the diagram shown
which best explains who is correct?
n = 2
n
=
1
lexy is correct because angle r is between the incident
wave, n = 0, and a diffracted wave.
lexy is correct because angle rincludes the diffracted
wave at n =
jin is correct because angle s is measured from the
barrier and includes n = 2, the wave that has the most
diffraction
jin is correct because angle s is between the dimmest
order bands, n = 1 and n = 2.
lexy says that the diffraction angle is the one labeled r
and jin says that the diffraction angle is the one labeled s
