Properties of electromagnetic waves
The following properties are common to all electromagnetic waves:
- Travel in a vacuum with a speed of 3.0x108m/s.
- Do not require material medium for their propagation.
- Transverse in nature.
- Posses and transfer energy. The amount of energy possessed by an electromagnetic wave of frequency f
is expressed as E= hf, where h is Plank’s constant and is equal to 6.63x10-9Js.
- Carry no charge (not charged) and are not deflected by a magnetic or electric field.
- Undergo reflection, refraction, diffraction, interference and polarization effects.
OR
Common properties:
i. They do not require a material medium and can travel through a vacuum.
ii. They undergo reflection, refraction and diffraction. iii.
All electromagnetic waves travel at the speed of light i.e. 3 × 108 ms-1.
iv. They carry no electric charge.
v. They transfer energy from a source to a receiver in the form of oscillating electric and magnetic.
