Lexy and jin study the diagram shown.
which best explains who is correct?
n
=
2
o 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 = 1
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 =
lexy says that the diffraction angle is the one labeled r
and jin says that the diffraction angle is the one labeled s.
