Question

Choose the correct answer from the alternatives given. Which of the following statement is false for the properties of electromagnetic waves ?

• A. Both electric and magnetic field vectors attain the maxima and minima at the same place and same time
• B. The energy in electromagnetic wave is divided equally between electric and magnetic vectors
• C. Both electric and magnetic field vectors are parallel to each other and perpendicular to the direction of propagation of wave
• D. These waves do not require any material medium for propagation

Answer 1

The correct option is C Both electric and magnetic field vectors are parallel to each other and perpendicular to the direction of propagation of wave

In an electromagnetic wave, the electrical and magnetic fields are perpendicular to each other and are perpendicular to the direction of propagation. They attain the maxima and minima at the same point and do not require any medium of propagation.
