Activity: Single slit diffraction

IB Physics: Activity: Single slit diffraction

When light passes through a narrow slit it spreads out, this is called diffraction. The light does not spread out uniformly but forms bright and dark areas as shown below.The width of the central maximum depends on the size of the slit, small slit gives wide maximum. With the apparatus set up as shown below the relationship between the angle θ and the slit size,a is:asinθ = λUsing the Vernier calliper as a slit form...
