NEET Physics Question - Electromagnetic Waves

**Assertion (A):** In an electromagnetic wave, both the electric and magnetic field vibrates with same phase and frequency.

**Reason (R):** Amplitude of vibration of electric and magnetic field are equal in an electromagnetic wave.

Both (A) &(R) are true and the (R) is the correct explanation of the (A)

Both (A) &(R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

In an EM wave, electric and magnetic fields oscillate in phase and with the same frequency. However, their amplitudes are related by \(E_0 = cB_0\) and are generally not equal. Thus, A is true, but R is false.
