Question
Find the wavelength of a radio wave from an AM station broadcasting at a frequency of $14 \overline{0} 0 \mathrm{kHz}$.
Step 1
The frequency is given as $1400 \, kHz$, which can be simplified to $1.4 \times 10^6 \, Hz$. The speed of light is given as $3 \times 10^8 \, m/s$. We are asked to find the wavelength, denoted as $\lambda$. Show more…
