Single slit.

  1. Dec 6, 2007 #1
    Light of wavelenght 630nm passes through a single slit. The angular deflection to the tenth dark band on the side of the center maximum is 3.6 degrees. A) Calculate the slit width. B) Calculate the angular deflection to the tenth dark band using light of 450 nm wavelenght.

    Relevent Equations :

    delta y = L(Lamda) over d.

    Convert degree into radian. Then angle theta = delta y/L = Lamda/d
