      • What is known as light is more properly called electromagnetic radiation. We know from experiments that light acts as a wave. As such, it can be described as having a frequency and a wavelength.

    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.

    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").

    Just notes so far. The speed of light in a vacuum is represented by the letter c from the Latin celeritas— swiftness. Measurements of the speed of light. Ole Rømer (1644–1710) Denmark. "Démonstration touchant le mouvement de la lumière trouvé par M. Roemer de l'Académie des Sciences." Journal des Scavans. 7 December 1676. Rømer's idea was to use th...

    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...

    If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.

    For example, when light encounters anything we can observe with unaided eyes, such as a mirror, it acts like a ray, with only subtle wave characteristics. We will concentrate on the ray characteristics in this chapter.

    For example, when visible light encounters anything large enough that we can observe it with unaided eyes, such as a coin, it acts like a ray, with generally negligible wave characteristics. In all of these cases, we can model the path of light as straight lines.
