Topic: EM waves, characteristics and transverse nature· Electromagnetic Waves
The property which is not of an electromagnetic wave travelling in free space is that :
1. they originate from charges moving with uniform speed.
2. they are transverse in nature.
3. the energy density in electric field is equal to energy density in magnetic field.
4. they travel with a speed equal to \(\frac{1}{\sqrt{\mu_0\epsilon_0}}\).
