Electromagnetic spectrum
What this topic asks you to be able to do
- give the statement that every electromagnetic wave is a transverse wave which moves at the same speed c through free space
- recall roughly how long the wavelengths in free space are for each main region of the electromagnetic spectrum, running from radio waves through to γ-rays
- recall that wavelengths of 400–700nm in free space are picked up by the human eye as visible light
