For the production of electromagnetic waves, the charges used are:
- A
Stationary charges
- B
Charges moving with uniform speed
- C
Accelerating charges
- D
All of the above
Electromagnetic waves are produced when charges undergo acceleration. Acceleration of charges creates changing electric and magnetic fields, which in turn generate electromagnetic waves. Therefore, accelerating charges are necessary for the production of electromagnetic waves.
Stationary charges do not produce electromagnetic waves. Electromagnetic waves are generated by the acceleration or oscillation of charges.
Charges moving with uniform speed do not produce electromagnetic waves. To generate electromagnetic waves, charges need to undergo acceleration or oscillation.
