Transfer of Energy by Electromagnetic Waves

  • Electromagnetic (EM) waves carry energy and so can transfer energy from one point to another point
  • EM waves with a shorter wavelength carry a higher energy
  • This includes UV, X-rays and gamma rays
  • The higher the energy of the EM wave, the more dangerous it is

Energy Transfer by Microwaves

  • Water molecules absorb certain wavelengths of microwave radiation
  • Therefore, microwave ovens transfer energy from the electronics to heat the food placed inside it

Energy transfer in a microwave ovenEnergy transfer in a microwave oven

Energy Transfer by Infrared

  • All hot objects emit infrared radiation
  • The emitted waves can then be absorbed by other objects, warming them up

Energy Transfers from the Sun

  • The Sun emits several types of EM radiation, including:
  • Visible light waves allow living creatures to see
  • Infrared waves heat up the Earth
  • Ultraviolet waves provide plants with the energy for photosynthesis which they need to grow
