Presentation Transcript


The instrument used to measure the temperature of a human body is called

  • an endoscope

  • an ohmmeter

  • an oscilloscope

  • a stethoscope

  • a thermometer


Which one of the following radiations is used in a laser?

  • Gamma rays

  • X-rays

  • Visible light

  • Microwaves

  • Radio waves


The activity of a radioactive source is measured in

  • becquerels

  • watts

  • coulombs

  • joules

  • sieverts


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.


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

Which of the following particles are in orbit around the nucleus of an atom?

  • Electrons only

  • Protons only

  • Electrons and protons

  • Protons and neutrons

A ray of light changes direction as it travels from air into water. This effect is called

  • Diffraction

  • Diffusion

  • Incidence

  • Refraction

  • Reflection

Skin cancer is most likely to be caused by excessive exposure to

  • radio waves

  • microwaves

  • infrared radiation

  • visible light

  • ultraviolet radiation
