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 :
[tex]c=f\lambda[/tex]
c is speed of light
[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{868\times 10^3}\\\\\lambda=345.62\ m[/tex]
So, the wavelength of its signal is 345.62 m
