Question

In the propagation of electromagnetic waves the angle between the direction of propagation and the plane of vibration is ________

• A. $\pi$
• B. $\frac{\pi }{2}$
• C. $\frac{\pi }{4}$
• D. $0$

Answer 1

The correct option is B $\frac{\pi }{2}$

Light waves are comprised of transverse waves in electric and magnetic fields.In transverse waves the angle between the direction of propagation and the plane of vibration is $\frac{\pi }{2}$
