NEET · Physics · STD 12 - 8. Electromagnetic waves
In an electromagnetic wave in free space the root mean square value of the electric field is \(E_{rms} = 6\, V m^{-1}\) The peak value of the magnetic field is
- A \(2.83 \times 10^{-9}\;T\)
- B \(4.83 \times 10^{-8}\;T\)
- C \(8.83 \times 10^{-8}\;T\)
- D \(2.83 \times 10^{-8}\;T\)
Answer & Solution
Correct Answer
(D) \(2.83 \times 10^{-8}\;T\)
Step-by-step Solution
Detailed explanation
\(\text { Given: } E_{\mathrm{rms}}=6 \,\mathrm{Vm}^{-1}\) \(\frac{E_{\mathrm{rms}}}{B_{\mathrm{rms}}}=c\) or \(B_{\mathrm{rms}}=\frac{E_{\mathrm{rms}}}{c}\)
