Light through water droplets in the bend so as to make separate colors and each color in the steered at different angles.

The amount of refracted light depends on the wavelength and color.

The wavelength of this light to form ribbons parallel lines called a spectrum.

In the droplets of water weve got a different color extends from one side to the other water droplets.

The overall effect is that the incoming light will be reflected back through the various angles with the most intense light at an angle of 40-42.

Rainbow can only be seen when there is rain accompanied with sunlight.

Also determines the position of the observer, ie between rain and sunshine, and the sun is behind the observer.

Resulting ina straight line between sun, observer, and the arc of the rainbow.

As a result of the rainbowformed from the results of refraction and observer positions earlier.

When sunlight through water droplets, the light bent in such a way that makes the colors that exist in the light separately.

So in the droplets of water, weve got a different color extends from one side to the other water droplets.

The common mnemonic I was taught to remember this is Richard Of York Gave Battle In Vain.
