Single Slit
 
Java runtime environment not installed or deactivated

Download:   Java application   Configuration file

 
Condition for a maximum (approximation):
 
α = 0°    or    b sin α  =  (k + ½) λ

b ... width of slit
α ... angle
k ... order of the maximum (1, 2, 3, ...)
λ ... wavelength

 
Condition for a minimum:
 
b sin α  =  k λ

b ... width of slit
α ... angle
k ... order of the minimum (1, 2, 3, ...)
λ ... wavelength
