Dispersion, Scattering, and Colors

Primary Colors of Light

1. Primary colors of light are red, green, and blue (RGB).
2. These colors are called primary because they cannot be produced by combining other colors of light.
3. When combined in equal proportions, they produce white light.
4. Primary colors are used in devices like TVs, monitors, and projectors for color mixing.
5. The RGB model is based on the additive color theory.

Scattering of Light

1. Scattering of light occurs when light interacts with particles in a medium and is deflected in different directions.
2. The intensity of scattered light depends on the wavelength of light and the size of the particles.
3. Shorter wavelengths (blue and violet) are scattered more than longer wavelengths (red and yellow).
4. This phenomenon is described by Rayleigh scattering for small particles.
5. When particles are compar

Dispersion of Light

1. Dispersion is the phenomenon where white light splits into its constituent colors when it passes through a prism.
2. It occurs due to the variation in the refractive index of the material for different wavelengths of light.
3. The order of colors in the visible spectrum is: Violet, Indigo, Blue, Green, Yellow, Orange, Red (VIBGYOR).
4. Isaac Newton was the first to demonstrate dispersion using a glass prism.
5. The angle of deviation is
