## Homework Statement

Question 1. General Plane Waves.

We may represent a general electromagnetic plane wave by (real part of the complex exponentials)

[itex]E=E_{0}*e^(i*

**k***

**r**-iwt) B=B_{0}*e^(i*

**k***

**r**-iwt)[/itex]

Show that Faraday's Law becomes iwB0=-ik x Eo

## Homework Equations

dB/dt=- curl of E

## The Attempt at a Solution

I transformed dB/dt into iwB0e^(ikr-iwt).

Attempted to perform curl of E on Eoe^(ikr-iwt) but not sure how to work with the r. I thought you might use curl in spherical polars but then you have theta and phi components and I think there's only x, y and z
