  4. No, sorry……… • You need to revise the electromagnetic spectrum. • With this link, please remember that often, the electromagnetic spectrum is pictured with the high energy waves (e.g. gamma rays) on the right hand side.

  5. Question 2: which of the people is the most likely to burn quickest when out on a sunny day? Click on the correct face.

  6. No, sorry…… • You need to revise how UV light can affect our skin: • Click here.

  15. No, sorry… • Watch this animation to get the correct answer.

  16. Question 6: In order for infrared radiation to be detected, it must be: • absorbed • reflected

  17. No sorry….. • See the animation on page 11 of the following link: • http://lgfl.skoool.co.uk/content/keystage4/physics/pc/lessons/uk_ks4_waves_2/h-frame-ie.htm

  18. Question 7: Which of the following types of radiation is ionising? • Visible light • Infrared • Ultraviolet • Microwave

  19. No, sorry… • You need to learn about ionising and heating radiation, and which types they include. Go to: http://www.bbc.co.uk/schools/gcsebitesize/science/21c/radiation/electromagneticradiationrev6.shtml

  20. Question 8: Which type of radiation do mobile phones use to communicate with the base station? • Infrared • Microwave • Gamma • Ultraviolet

  21. No, sorry… • Go to http://www.bbc.co.uk/schools/gcsebitesize/science/21c/radiation/hazardsradiationrev3.shtml
