The wavelength of a 2.4 GHz wave in free space is about

  • A.12.5 cm
  • B.2.4 cm
  • C.1.25 cm
  • D.125 cm

Answer: A

Dividing three times ten to the eighth by 2.4 times ten to the ninth gives 0.125 metres. A half-wave antenna at that frequency is about six centimetres long, which is why wireless equipment at this band can be so small.
