An electromagnetic wave moves in vacuum. Its speed is (c), choose the correct options about the characteristics of electromagnetic waves

(A) $c =\frac{1}{μ_0ε_0}$
(B) electromagnetic waves are transverse in nature.
(C) both the electric field and the magnetic field vibrate perpendicular to the direction of propagation of waves.
(D) electromagnetic waves are longitudinal in nature.

Choose the correct answer from the options given below:

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

The correct answer is Option (1) → (A), (B) and (C) only

Electromagnetic waves in vacuum have the following characteristics:

(A) True: $c = \frac{1}{\sqrt{\mu_0 \epsilon_0}}$

(B) True: Electromagnetic waves are transverse.

(C) True: Both $\vec{E}$ and $\vec{B}$ fields are perpendicular to the direction of propagation and to each other.

(D) False: Electromagnetic waves are not longitudinal.

Correct options: A, B, C
