Question:

What is the wavelength range of super high frequency waves ?

Options:

1 m - 10 m

1 cm - 10 cm

1 m - 1 km

10 m - 100 m

Correct Answer:

1 cm - 10 cm

Explanation:

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
