1. Light
A special kind of wave!

2. Light is only one of a whole family of useful waves!
Radio Microwaves Infra-Red Visible light Ultra-violet X-rays Gamma rays
Next?

3. One wave we can see!
Light is only one small part of a whole range of waves called the electromagnetic spectrum
Gamma rays
X-rays
ultraviolet
Visible light
infrared
microwaves
radio waves
Short wavelength long wavelength

4. Remember the waves in electromagnetic spectrum?
Use this phrase to help you…

Radio waves
Microwaves
Infra red
Visible light
Ultra violet
X rays
Gamma rays

5. Visible light
Visible light is only a very small part of the electromagnetic spectrum
Light that we can see can be split up as it passes through a prism.
We can then see these different colours known as the visible spectrum.
A rainbow is formed when light is split up as it passes through raindrops.

6. Can you remember the spectrum colours?
Red
Orange
Yellow
Green
Blue
Indigo
Violet

7. Where does visible light fit in?
Gamma rays
X-rays
ultraviolet
Visible light
infrared
microwaves
radio waves
Notice where ‘violet’ light is?.... Next to Ultra violet rays!
Notice where ‘red’ light is?.... Next to Infra red rays!

8. Time to test yourself!
You have seen that visible light waves are only one small part of a range of useful waves called the electromagnetic spectrum
There are seven types of waves in the electromagnetic spectrum – remember the rabbit rhyme?
Visible light can be split into seven colours – called the visible spectrum – remember ROY G BIV
