Place the different forms of electromagnetic radiation in order from the highest energy to the lowest energy, from the rays that are most damaging and have a short wavelength to the rays that are the least damaging and have a long wavelength.
| 1 | Visible light which is the only part that our eyes can detect. |
|---|---|
| 2 | Microwaves are longer than infra -red but have less energy. |
| 3 | Gamma rays come from nuclear explosions and are very damaging to humans. |
| 4 | X-rays can also damage humans and cause cancer. |
| 5 | Radio waves are long waves that can penetrate the atmosphere. |
| 6 | Infra-red which we can feel but not see. |
