JEE Main 2023 — Electromagnetic Waves Question with Solution

In an electromagnetic wave, the maximum value of the electric field E is related to the maximum value of the magnetic field B by the equation

$E=cB$

where c is the speed of light in a vacuum, which is approximately $3\times 10^{8}m/s$.

Given that the amplitude of the magnetic field B is $6.0\times 10^{-7}T$, we can substitute these values into the equation to find the maximum value of the electric field:

$E=(3\times 10^{8}m/s)\times (6.0\times 10^{-7}T)=180V/m$

Therefore, 180 V/m is the correct answer.
