May 24, 2024 · Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other). Figure 2.1.1 – Electromagnetic Wave. The red arrows in the figure above ...
Light scattered from the atoms in the box will be polarized because the "blue" polarization cannot travel in the direction shown due to the required transverse nature of the light wave 4. Polarization by reflection : Similar to the scattering situation, there is a particular angle of reflection from a surface at which the reflected light is linearly polarized.
Apr 10, 2022 · The nice thing about a wave is that it is a repeating phenomenon. Whether it is the up-and-down motion of a water wave or the changing electric and magnetic fields in a wave of light, the pattern of disturbance repeats in a cyclical way. Thus, any wave motion can be characterized by a series of crests and troughs (Figure \(\PageIndex{3}\)).
Ray optics is great in its simplicity, but there are aspects of light that cannot be explained by this model. We can expand our model to include the wave nature of light. This new model is known as wave optics. Treating light as a wave allows us to understand and quantify phenomena such as interference and diffraction.
Section Summary. A straight line that originates at some point is called a ray. The part of optics dealing with the ray aspect of light is called geometric optics. Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; (3) after being reflected from a mirror.

The law of reflection states that the angle of reflection * is equal to the angle of incidence. Light rays that pass through an interface are transmitted rays. These rays bend. This bending is called refraction. The direction and magnitude of refraction depends on the relative densities of the two media and the angle of incidence.
