Question:medium
Which one of the following is the property of a monochromatic, plane electromagnetic wave in free space?
Which one of the following is the property of a monochromatic, plane electromagnetic wave in free space?
Show Hint
To remember the speed relation, think of the alphabet: E comes before B, so \( E \) is in the numerator: \( c = E/B \)
Updated On: May 6, 2026
- Electric and magnetic fields have a phase difference of \( \pi/2 \)
- The energy contribution of both electric and magnetic fields are equal
- The direction of propagation is in the direction of electric field E
- The pressure exerted by the wave is the product of energy density and the speed of the wave
- The speed of the wave is B/E
Show Solution
The Correct Option is B
