The Wave Nature of Light

Waves vs Particles

Huygens’ Principle Every point on a wave front can be considered as a source of tiny wavelets that spread out in the forward direction at the speed of the wave itself. The new wave front is the envelope of all wavelets – the tangent to all of them.

The bending of waves behind the obstacles into the “shadow region” is known as diffraction.

Huygens’ Principle and the Law of Refraction

Important: When a light wave travels from one medium to another, its frequency does not change, but its wavelength does.

Interference: Young’s Double Slit Experiment

Constructive Interference: Destructive Interference:

Line Spacing for Double-Slit Interference

Conceptual Example: Changing the Wavelength What happens to the interference patter if the incident light (500 nm) is replaced by light of wavelength 700 nm? What happens instead if the slits are moved farther apart?
