1. What two properties are common to all types of electromagnetic radiation? They travel at the speed of light and they can travel across a vacuum Answer Next question

2. Which type of electromagnetic radiation has the longest wavelength ? Radio Answer Next question

3. Name the two examples of ionising radiation in the electromagnetic spectrum Gamma and X-rays ( very high frequency UV may also be ionising) Answer Next question

4. Name the three examples in the electromagnetic spectrum which are known to cause cancer gamma X rays ultra violet Answer Next question

5. Which type of electromagnetic radiation is used for satellite communication ? microwaves ( these pass through the atmosphere, unlike radio waves ) Answer Next question

6. What is the correct name for heat radiation ? Infra red Answer Next question

7. Which type of radiation can cause a sun tan or skin cancer ? Ultra violet Answer Next question

8. Which type of electromagnetic radiation is a type of radioactivity ? Gamma Answer Next question

9. Why is sound not part of the electromagnetic spectrum ? it does not travel at the speed of light and it cannot pass through a vacuum Answer Next question

10. Which type of electromagnetic radiation is absorbed by water ? Microwaves – this is why they are useful for cooking Answer Next question
