- All electromagnetic waves travel at the same speed in a vacuum. They all travel at the speed of light:3 x 108 m/s (or 299,792,458 m/s)
- Wavelength - 103 mFrequency - 104Hz
- Wavelength - 10-2 mFrequency - 108Hz
- Wavelength - 10-5 mFrequency - 1012Hz
- Radio waves are used in radio telescopes to study far away objects in space. Radio waves are also used for RADAR, broadcasting, and communication.
- Microwaves can be used for communication between mobile phones. Microwaves can also be used to heat food. Microwaves cause the water molecules in food to get warmer.
- Infrared radiation is used for thermal imaging. Infrared rays are also used for cooking food in toaster ovens. IR is used to control your TV from your remote as well.
