The waves used for line-of-sight (LOS) communication is

Options

  1. Aground waves
  2. Bspace waves
  3. Csoundwaves
  4. Dsky waves

Correct answer

B. space waves

Step-by-step solution

Space waves are used for line-of-light (LOS) communication. Line-of-sight is a type of communication that can transmit and receive data only when transmitter and receiver stations are in view of each other with no obstacle between them.
