How do we know light is a wave

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 ...
