Sagot :
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]
