2. Microwaves- mobile phones, shortest wavelength (non ionising)
3. Infra red- Toaster (non ionising)
4. Visible light- we can see it (non ionising)
5. UV- suns radiation can lead to skin cancer (ionising)
6. x-rays- HIgh frequency (ionising)
Gamma rays- Used to treat/kill cancer cells, highest frequency (ionising)
Ionisation- Happens when a photon with enough energy hits an atom/molecule inside a material
