Question

A new radio station, KHEM-AM, broadcasts
at a frequency of 868 kHz. What is the wavelength of its signal?
Answer in units of meters.

Answer 1

Answer:

wavelength = 345.62 m

Explanation:

Given that,

Frequency of signal, f = 868 kHz

We need to find the wavelength of its signal.

The relation between wavelength and frequency is given by :

$c=f\lambda$

c is speed of light

$\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{868\times 10^3}\\\\\lambda=345.62\ m$

So, the wavelength of its signal is 345.62 m
