Calculate the electric and magnetic fields produced by the radiation coming from a `100` W bulb at a distance of `3 m`. Assume that the efficiency of the bulb is `25%` and it is a point source.

Explanation

To calculate the electric and magnetic fields produced by the radiation from a 100 W bulb at a distance of 3 m, we can follow these steps:

### Step 1: Determine the output power of the bulb
Given that the efficiency of the bulb is 25%, we can calculate the output power (P) as follows:

\[ P = \text{Efficiency} \times \text{Input Power} \]
