Young's double-slit experiment is carried out by using green,red,and blue light,one color at a time. The fringe widths recorded are $\beta_G, \beta_R$,and $\beta_B$ respectively. Then:

  • A
    $\beta_G > \beta_B > \beta_R$
  • B
    $\beta_B > \beta_G > \beta_R$
  • C
    $\beta_R > \beta_B > \beta_G$
  • D
    $\beta_R > \beta_G > \beta_B$
