Solution


Q.

The property which is not of an electromagnetic wave travelling in free space is that              [2024]
 
1 they are transverse in nature.  
2 the energy density in electric field is equal to energy density in magnetic field.  
3 they travel with a speed equal to 1μ0ε0.  
4 they originate from charges moving with uniform speed.  

Ans.

(4)

When charge is accelerated then, time-varying electric and magnetic fields are produced, thus electromagnetic wave is produced by accelerated charge.
