  1. The instrument used to measure the temperature of a human body is called • an endoscope • an ohmmeter • an oscilloscope • a stethoscope • a thermometer

  2. Which one of the following radiations is used in a laser? • Gamma rays • X-rays • Visible light • Microwaves • Radio waves

  3. The activity of a radioactive source is measured in • becquerels • watts • coulombs • joules • sieverts

  4. Gamma radiation is used in hospitals to sterilise instruments. This is because gamma radiation • makes the instruments radioactive • increases the temperature of the instruments • reduces the temperature of the instruments • destroys any living cells on the instruments • makes the instruments glow in the dark.

  5. Which of the following is a use for ultrasound in medicine? • Correcting eye defects such as a detached retina • Killing cancerous cells • Producing an image of an unborn baby • Removing “port wine” birth marks • Sterilising medical instruments

  6. The card covers which shape of glass? • Concave lens • Convex lens • Prism • Rectangular block • Semi-circular block

  7. Sounds can travel through • A vacuum • Solids only • Liquids only • Gases only • Solids, liquids and gases.

  8. The instrument used to detect sounds produced within the human body is called • An oscilloscope • An endoscope • A stethoscope • A thermogram • A spectroscope

  9. Which of the following particles are in orbit around the nucleus of an atom? • Electrons only • Protons only • Electrons and protons • Protons and neutrons • Protons, neutrons and electrons

  10. A ray of light changes direction as it travels from air into water. This effect is called • Diffraction • Diffusion • Incidence • Refraction • Reflection

  11. Which of the radiations alpha, beta or gamma would be stopped by a sheet of aluminium 5mm thick? • Alpha only • Beta only • Gamma only • Alpha and beta only • Beta and gamma only

  12. The nucleus of a uranium atom contains • electrons only • neutrons only • electrons and protons only • protons and neutrons only • electrons, protons and neutrons

  13. What is the unit of equivalent dose? • becquerel • joule • kilogram • sievert • watt

  14. The diagram shows a ray of light reflected from a plane mirror. A plane mirror Which of the labelled angles is the angle of relection? • A • B • C • D • E B C E D

  15. Which of the following radiations is used to detect broken bones? • Gamma rays • Infrared rays • Light rays • Ultraviolet rays • X-rays

  16. Skin cancer is most likely to be caused by excessive exposure to • radio waves • microwaves • infrared radiation • visible light • ultraviolet radiation

  17. Which entry gives the correct units used for dose equivalent and the activity of a radioactive source?

  18. What is the name of the glass shape used to split white light into different colours? • Concave lens • Convex lens • Prism • Rectangular block • Semi-circular block

  19. In a solid metal conductor, the current is a flow of • electrons • protons • neutrons • protons and electrons • Protons and neutrons

  20. Which of the following shows the correct path of a ray of light passing through air and into a block of glass 1. 4. 2. 5. 3.

  21. The diagram shows how radiations X and Y from a radioactive source are affected when materials are placed in front of the source. 2mm aluminium 2cm lead Which of the following correctly names both radiations? X source Y paper
