Scattering of Light: by small particles and molecules in the atmosphere. Different from reflection, where radiation is deflected in one direction, some particles and molecules found in the atmosphere have the ability to scatter solar radiation in all directions.

The Short Answer: Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Light can be examined entirely from its source. When light passes from one medium to any other medium say air, a glass of water then a part of the light is absorbed by particles of the medium preceded by its subsequent radiation in a particular direction. This phenomenon is termed as a scattering of light.

As previously stated, Rayleigh scattering is inversely proportional to the fourth power of wavelength, so that shorter wavelength violet and blue light will scatter more than the longer wavelengths (yellow and especially red light).

If dispersion does not occur in nature, then there is no rainbow formation and splitting of light into seven different colors. If there is no scattering then the oceans and sky appears to be black.

Particles in water can scatter light. Light scattering by suspended matter is required in order that the blue light produced by water’s absorption can return to the surface and be observed.

Scattering is proportional to one divided by wavelength to the fourth power. In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together.

Violet

violet light

Out of all the colours in VIBGYOR, that is Violet, Indigo, Blue, Green, Yellow, Orange, and Red, Violet has the maximum angular deviation, and Red has the least or minimum angular deviation.

when the white light falls on the prism, every colour is refracted by a different angle. and violet deviates the most and red deviates the least.

violet colour

Red colour has the highest wavelength, i.e. 620-750nm (and Violet has the least, i.e. 380-450 nm) besides also the lowest frequency. This is why red moves more quickly than the other colours and bends the least (and violet bends the most).

Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum. Water droplets in the air can act in a manner similar to that of a prism, separating the colors of sunlight to produce a spectrum known as a rainbow.

In a primary rainbow, the colors will be in the order of red, orange, yellow, green, blue, indigo and violet. Or ROYGBIV. Red has the longest wavelength, with each color decreasing away from it.

Try to remember the name of an imaginary person called Roy G. Biv. The letters in this name correspond to the order of the colors of the rainbow….The letters break down like this:

1. R stands for Red.
2. O stands for Orange.
3. Y stands for Yellow.
4. G stands for Green.
5. B stands for Blue.
6. I stands for Indigo.
7. V stands for Violet.

Rainbows appear in seven colors because water droplets break white sunlight into the seven colors of the spectrum (red, orange, yellow, green, blue, indigo, violet). You might be able to see a second rainbow above the main one in which the colors are in reverse order.

The colours of the rainbow are Red, Orange, Yellow, Green, Blue, Indigo and Violet.

They are: red, orange, yellow, green, blue, and violet….red green blue.

What does the number 7 smell like? An electrical fire. 7 smells like 9 because 7 8 9!
