Does white light contain only the wavelengths of visible spectrum (i.e only from 400nm to 800nm)?
White light is a combination of all the colors in the visible spectrum, while visible spectrum refers to the colors of light that are visible to the human eye.
Yes, using a prism or a diffraction grating, white light can be separated into its component colors of red, orange, yellow, green, blue, indigo, and violet.
White light is often used in experiments and demonstrations because it contains all the colors of the visible spectrum, making it easier to observe and study the properties of light.
The visible spectrum is significant because it is the range of electromagnetic radiation that our eyes are sensitive to and allows us to see the colors of the world around us.
The wavelength of light directly affects its color. Shorter wavelengths appear blue or violet, while longer wavelengths appear red or orange. The visible spectrum ranges from approximately 400-700 nanometers in wavelength.
