From radio waves to gamma rays, the electromagnetic spectrum is useful in different ways. How does this radiation differ and how can they be used?
- Electromagnetic radiation exists along a continuous range, exhibiting different properties.
- The Electromagnetic Spectrum covers low/high-frequency, long/short-wave radiation.
- Long-wave, low-frequency radio waves give us TV and Radio.
- Short-wave, high-frequency Gamma Rays ionise and destroy cancer cells.
The electromagnetic spectrum is the continuous range of electromagnetic radiation that exists all around us.
The properties of the waves vary greatly – from extremely low frequency, long wavelength radiation to high frequency, short wavelength radiation.
The different types of radiation can be useful in very different ways.
Radio waves are ...
