JEE Mains · Physics · STD 12 - 8. Electromagnetic waves
The amplitude of magnetic field in an electromagnetic wave propagating along \(y\)-axis is \(6.0 \times 10^{-7}\,T\). The maximum value of electric field in the electromagnetic wave is:
- A \(5 \times 10^{14}\,Vm ^{-1}\)
- B \(180\,Vm ^{-1}\)
- C \(2 \times 10^{15}\,Vm ^{-1}\)
- D \(6.0 \times 10^{-7}\,Vm ^{-1}\)
Answer & Solution
Correct Answer
(B) \(180\,Vm ^{-1}\)
Step-by-step Solution
Detailed explanation
\(\frac{E}{B}=C\) \(E=B C\) \(=6 \times 10^{-7} \times 3 \times 10^8\) \(=18 \times 10\) \(E =180\,Vm ^{-1}\)
