  1. P1 foundation

  2. House Insulation Methods How many can you name?

  3. Uses V IR R M UV G X Long frequency Low wavelength High energy Dangers No dangers most dangerous least

  4. Uses Taking pictures of bones Cooking food and mobiles Remote controls and thermal imaging Sun beds, fluorescent tubing, security marking Killing cancer cells, sterilising hospital equipment Seeing, optical fibres Transmits information over radios Infra-red Visible Radiowaves Microwaves Ultra-violet Gamma rays X-ray Long wavelength Low frequency Low energy Long wavelength High frequency High energy Dangers Even low doses can kill healthy cells Can burn skin over time Can damage eyes if too intense High doses can kill healthy cells Burns skin, can cause skin cancer Heating water in tissue – can burn

  5. P1 higher

  6. Does it reduce conduction, convection or radiation?

  7. Energy = mass x SHC x change in temp transferred

  8. Uses V IR R M UV G X Long frequency Low wavelength High energy Dangers No dangers most dangerous least
