Light characteristics refer to the properties that define how light behaves and interacts with different materials. These properties include wavelength, frequency, and intensity. The wavelength determines the color of the light, while frequency relates to how often the light wave oscillates. Intensity measures the brightness of the light. Another important characteristic is polarization, which describes the orientation of light waves. Light can be polarized in different directions, affecting how it interacts with surfaces and materials. Additionally, refraction occurs when light passes through different mediums, causing it to change direction and speed. These characteristics are essential in fields like optics and photography.
