    May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

    When a light ray encounters a surface, one or more of the following three things occur, the light ray: Reflects off the surface and travels off in a different direction. Passes from one medium into the other and continue on a new, straight line path. Is absorbed. Often, more than one of these occur.

    Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization. 1. In 1678, Christiaan Huyg...

    Light is produced by one of two methods… 1. Incandescenceis the emission of light from "hot" matter (T ≳ 800 K). 2. Luminescence is the emission of light when excited electrons fall to lower energy levels (in matter that may or may not be "hot").

    The amplitude of a light wave is related to its intensity. 1. Intensityis the absolute measure of a light wave's power density. 2. Brightnessis the relative intensity as perceived by the average human eye. The frequency of a light wave is related to its color. 1. Coloris such a complex topic that it has its own section in this book. 2. Monochromati...

  5. www.physicsclassroom.com › class › lightPhysics Tutorial: Wavelike Behaviors of Light

    Light behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would. Yet there is still more reason to believe in the wavelike nature of light. Continue with Lesson 1 to learn about more behaviors that could never be explained by a strictly particle-view of light.

    Using a light source that emits a single wavelength of light (known as monochromatic, as it only has one wavelength of light present), the presence of interference fringes (patterns of dark and light spots) can be used to determine the flatness of a gap between two surfaces.
