VIDEO OF DIFFRACTION EXPERIMENTS
AN APPLET WHICH DEMONSTRATES SINGLE SLIT DIFFRACTION:
DIFFRACTION
Diffraction can be understood with reference to Huygen's secondary wavelets or you can consider the different distances that rays diffracted by an object take.
DIFFRACTION PATTERN VARIABLES SIMULATION
Sketch the variation with angle of diffraction of the relative intensity of light diffracted at a single slit.
Derive the formula θ = λ/b for the position of the first minimum of the diffraction pattern produced at a single slit.
On the diagram below, the path difference is λ/2 for a minimum.
sinθ = λ/a. Using small angle approximation and IB notation, θ = λ/b
Slit width is a here, in IB equation it is b
Solve problems involving singleslit diffraction.
