Question

H0ow many orders of diffraction do you get and why

Answer 1

Diffraction from a single slit. Young's experiment with finite slits. Diffraction pattern from a single slit. First order minima. Higher order minima. Intensity I(θ) Graphing I(θ) with the phasor sum. Varying the slit width. Young's experiement with finite slit width. Further reading.The single slit. When light passes through a single slit whose width w is on the order of the wavelength of the light, then we can observe a single slit diffraction pattern on a screen that is a distance L >> w away from the slit. The intensity is a function of angle.
