Calculate the length of half wave dipole antenna at `40 MHz`. Given `c=3xx10^(8)ms^(-1).`

Explanation

To calculate the length of a half wave dipole antenna at a frequency of 40 MHz, we can follow these steps:

### Step 1: Convert the frequency from MHz to Hz
The frequency given is 40 MHz. To convert this to Hertz (Hz), we use the conversion factor:
\[ 1 \text{ MHz} = 10^6 \text{ Hz} \]
Thus,
...
