Wave Properties of Light. Dispersion

Wave Properties of Light. Dispersion We often face this phenomena in our lives. However, we hardly ever notice it. But if you pay more attention, you'll see that dispersion always accompanies us. For example, it manifests itself in a rainbow. I bet you will not find a person who has never admired the rainbow.At first sight, the rainbow may seem very simple for you. However, it includes complex physical processes.Dispersion of light stands for a ratio between the light refraction factor and the light wave length. Newton's prism experiment as part of which white light is decomposed into the spectrum using a trihedral prism experimentally proves the phenomenon of dispersion.Newton proved that if white light passes through a glass prism it will decompose into seven rainbow colors i.e. red, orange, yellow, green, blue, indigo and violet. This means that white light is not actually white. Vice versa, it includes all of the above colors.Dispersion occurs as light rays with different wave length propagate in transparent substance i.e. optical environment at different speeds.Generally, the smaller wave length is, the greater the refraction factor and the smaller light speed will be.Incandescent solid and fluid bodies yield a continuous spectrum while incandescent gases yield a discrete spectrum typical of such substance only.Then, you see that light is white but the world is colorful!

This computer translator SUCKS!

[mavishill]

double rainbow!

[ronald3729]

Russian i saw the CCCP on the helmet at 0:2

[Jjunior130]

@mavishill its so intense T-T

[Megamadsta]

The talking in the background was really irritating but there was good info i guess.

[MucusFelidae]

I hate talking faces.

Educational videos can be made without them.

Just show what's important and comment in the background.

@mavishill The rainbow is always double! The problem is that background (clouds for example) is not always dark enough to see second bow.

@MenteDeChristo Yeah, but the info is pretty good
