A science centre is preparing a table showing the radiation used for four demonstrations.
| Demonstration | Type of electromagnetic radiation |
|---|---|
| producing an image of a person in complete darkness using radiation emitted by their body | |
| taking a colour photograph of a bird in daylight | |
| sending signals from a ground station to a satellite in orbit | |
| destroying cancer cells with a focused beam from a radioactive source |
Complete the table.
104 exam-style questions on Edexcel GCSE Physics 5.4 Uses and dangers of EM radiation, covering 5.4.1 Dangers of electromagnetic radiation, 5.4.2 Uses of electromagnetic radiation, 5.4.3 Radio waves and oscillations in circuits, and 5.4.4 Changes in atoms and nuclei generating radiation. Each one has a worked solution and a mark scheme showing where the marks go.
