Question

Which of the following is wrong?
A) Electromagnetic waves cause magnetic and electric fields.
B) Light is not propagated in vacuum.
C) Electric and magnetic fields are perpendicular to each other,
D) All electromagnetic radiations travel with same speed.​

Answer 1

Answer:

Correct option is C)

In electromagnetic waves,

1. The electric field and magnetic field varies continuously with time and have maxima and minima at same place and at same time.

2. Both electric and magnetic field have same energy.

3. both electric and magnetic field are perpendicular to each other and perpendicular to direction of propagation.

4. These waves don't require any material medium to propagate, they can propagate in vacuum as well.

So, the false statement will be the statement given in the option (C)
