Each of these waves have differnet wavelengths and frequencies giving them different properties. Some even have dangers.
Radio waves- large wavelength and low frequency. Wavelengths longer than about 10 cm
Micro waves- Used in comunication, shorter wavelength and higher frequency, DANGER absorbed by water molecules and heats them up- if this is in you cells cooks you!
Infra Red- Slightly shorter wavelength and larger frequency, used for detection in bergular alarms and TV romote controls, carries heat
Visible Light- Medium wavelength and frequency, light we can see, only dangerous if very bright as can damage retaners.
Ultra Violet- Shorter wavelength and larger frequency, releaced by the sun, used for checking forged bank notes, DANGER UV rays damage DNA in the cell causing skin canser.
X-rays- shorter wavelength and larger frequency, used in medicine to look at peoples bones,DANGER x-rays can cause mutations leading to cancer.
