Hello,

It is Dispersion.

Dispersion: light splitting up into various wavelengths, eg a rainbow, or light passing through a prism.

Diffraction: spreading out of waves as they pass through a small hole or around objects

Dispersion! Its the reason the sky is blue and we get fantastic sunrises and sunsets!

Dispersion is splitting up the light in different colors when passing thorough a media with refraction depending of the light wavelength

The splitting of white light into its seven constituent colours is called Dispersion

Dispersion! Its how the light get split into the rainbows

Its dispersion. It results in white light splitting into its component colours and was the way scientists discovered infra red and ultra violet waves

Dispersion. The splitting of light when it travels into a prism is called dispersion. The splitting is caused by refraction. Refraction occurs when light moves from one material to another. Each wavelength of light is refracted through a different angle, so the colours separate.

One of the most famous effects of dispersion is the rainbow. These are always good to see, but there are many more atmospheric light effects to look out for.

In this image you can see a halo around the sun, two sundogs (parhelia) on the left and right of the halo, an upper tangent arc (on top of the halo), a parhelic arc (going through the two sundogs) and infralateral arcs (far left and right of the image). These are all caused by ice crystals refracting light.

Look here for some other light effects you may see in the atmosphere. I would really like to see the spooky Brocken Spectre. Light really is fantastic.

The splitting up of light is called dispersion

Dispersion of light

Dispersion of light

Complete the sentence: The splitting up of light is called dispersion.

Dispersion, but most exams will also allow you to just describe this as the refraction of light!
