WebThe amplitude of a light wave is related to its intensity. Intensity is the absolute measure of a light wave's power density. Brightness is the relative intensity as perceived by the average human eye. The frequency of a light wave is related to its color. Color is such a complex topic that it has its own section in this book. WebOne of the most important wave-like behaviors of light is reflection. It is reflected light that we see with our eyes. How light reflects off objects affects the colors we see as well. When a wave strikes a new medium, some of the wave will bounce off the surface. How reflective the surface is will determine how much light (and what wavelengths ...

WebWe catch glimpses of its nature when a sunbeam angles through a dust-filled room, when a rainbow appears after a storm or when a drinking straw in a glass of water looks disjointed. These glimpses, however, only lead to … WebJul 2, 2024 · Since light is an electromagnetic wave, that means that the speed of light is equal to the speed of the electromagnetic waves. and are properties of the vacuum and are constants, so will also be a constant. Thus from Maxwell's theory of electromagnetism alone we can already see that the speed of light in vacuum should be constant. chuckle and roar fishing
