13 Ιουλ 2022 · Interference occurs whenever two or more waves combine to produce a resultant wave with a new resultant displacement; The waves combine according to the principle of superposition. Constructive interference happens when the resultant wave has a larger displacement than any of the individual displacements
Intensity of a wave’s radiation at a certain distance from the source. Transmitted intensity of light incident on a polariser (Malus’s law). n1/n2 = Index of refraction.
Test Yourself. Two-Slit Interference Patterns. For two-source interference fringes to be observed, the sources of the wave must be: Coherent (constant phase difference) Monochromatic (single wavelength) When two waves interfere, the resultant wave depends on the phase difference between the two waves.

The phenomenon of redistribution of light energy in a medium on account of superposition of light waves from two coherent sources is called interference of light waves. Young performed the experiment by taking two coherent sources of light.

Lesson Takeaways. I can qualitatively and quantitatively interpret cases of constructive and destructive interference I can add up two waves with superposition to create a new waveform I can use wavelength and source distance to identify maxima and minima for interference.
