S-Band wavelength is approximately which of the following?

Explanation:
Wavelength is inversely related to frequency: lambda = c / f. S-Band spans roughly 2 to 4 GHz, so the wavelengths are about 0.15 m (15 cm) at 2 GHz down to 0.075 m (7.5 cm) at 4 GHz. The middle of that range corresponds to about 0.10 m, or 10 cm. So the S-Band wavelength is approximately 10 cm. The other options lie outside this range: 1 cm would require ~30 GHz, 3 cm about 10 GHz, and 30 cm about 1 GHz.
