What is the wavelength range of super high frequency waves ?
Answer & explanation
Correct answer: option 2
The frequency range of super high frequency is 3 GHz to 30 GHz.
\(\lambda\) = \(\frac{c}{\nu}\)
\(\lambda\)1 = \(\frac{3*10^8 m/s}{30*10^9 /s}\) = 0.01 m = 1 cm
\(\lambda\)2 = \(\frac{3*10^8 m/s}{3*10^9 /s}\) = 0.1 m = 10 cm
