JEE-Level Practice: Electromagnetic Waves

A focused JEE Main / Advanced practice quiz — displacement-current computations, B inside charging capacitors, plane-wave equation reading (k, omega, directions via $\hat E\times\hat B$), media via $\sqrt{\mu_r\varepsilon_r}$, and spectrum ordering. Compute cross products and conversions; never answer from memory alone.
