which of the following statement is false for the properties of electromagnetic waves?
Options
(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.
Correct Answer:
Both electric and magnetic field vectors are parallel to each other and perpendicular to the direction of propagation of wave.
Explanation:
Electromagnetic waves are the combination of mutually perpendicular electric and magnetic fields. So, option (c) is false.
