AP EAMCET · PHYSICS · Electromagnetic Waves
For plane electromagnetic waves propagating in the positive Z - direction. The combination which gives the correct possible direction for \(\bar{E}\) and \(\bar{B}\) fields respectively is
- A \((-2 i-3 j)\) and \((3 i-2 j)\)
- B \((3 i+4 j)\) and \((4 i-3 j)\)
- C \((i-2 j)\) and \((-2 i-j)\)
- D \((-2 i+3 j)\) and \((i+2 j)\)
Answer & Solution
Correct Answer
(A) \((-2 i-3 j)\) and \((3 i-2 j)\)
Step-by-step Solution
Detailed explanation
As, \(\overrightarrow{\mathrm{E}} \perp \overrightarrow{\mathrm{B}} \Rightarrow \overrightarrow{\mathrm{E}} \cdot \overrightarrow{\mathrm{B}}=0\)…
