- These waves do not carry any charge
- These waves are not deflected by electric and magnetic fields
- They travel with the speed of light $\left( {c = 3 \times {{10}^8}\;m/s} \right)$ in vacuum
- The frequency of electromagnetic waves does not change when it goes from one medium to another but its wavelength changes
- These waves are transverse in nature, hence they can be polarised
