Answer :

Answer:

1 m

Explanation:

We start by the formula one should know to correlate wavelength and frequency:

phase velocity = wavelength * frequency

From which one obtains:

wavelength = (phase velocity) / frequency

We need phase velocity. We must assume something, for example, the wave of of electromagnetic radiation (= light). In this case, the phase velocity is the physics constant c = 300 000 000 m/s = [tex]3 \cdot 10^8 m/s[/tex]

We can now compute the wavelength, but we firstly should convert the frequency in Hz:

[tex]300 MHz = 300 \cdot 10^6 Hz = 3 \cdot 10^2 \cdot 10^6 Hz = 3 \cdot 10^8 Hz[/tex]

wavelength = [tex]\frac{3 \cdot 10^8 m/s}{3 \cdot 10^8 Hz} = 1 m[/tex]
