Which of the following statements are true about electromagnetic waves?

(A) Accelerated charges radiate electromagnetic waves.
(B) The frequency of the electromagnetic wave equals the frequency of oscillation of the charge.
(C) No material medium is involved in the vibrations of the electric and magnetic fields.
(D) Electromagnetic waves of different wavelengths have different velocities in free space/vacuum.

Choose the correct answer from the options given below:

(A), (B) and (C) only

The correct answer is Option (2) → (A), (B) and (C) only

(A) True: Accelerated charges radiate electromagnetic waves.

(B) True: The frequency of the EM wave equals the frequency of oscillation of the charge.

(C) True: No material medium is required; fields oscillate in free space.

(D) False: In free space/vacuum, all EM waves travel with the same speed $c = 3 \times 10^8 \, \text{m/s}$.

Correct statements: (A), (B), (C)
