Wavelength is a measure of the distance between two successive points in a wave. In the case of light, the wavelength refers to the distance between two successive crests or troughs in the electromagnetic wave.
Light is a form of electromagnetic radiation, and its wavelength determines its color. Different colors of light have different wavelengths. For example, red light has a longer wavelength than blue light.
The range of visible light wavelengths is typically considered to be between 400 and 700 nanometers (nm), with violet light having the shortest wavelength and red light having the longest wavelength.
In addition to visible light, there are also other forms of electromagnetic radiation with longer or shorter wavelengths than visible light. For example, radio waves have longer wavelengths, while X-rays and gamma rays have shorter wavelengths.
The wavelength of light affects how it interacts with matter. For example, when light passes through a prism, it is separated into its component colors due to the different wavelengths bending at different angles. This phenomenon is known as dispersion.
Overall, the wavelength of light is an important characteristic that determines its color and how it interacts with its surroundings.
