Why can we not use sky waves for navigation?(a) Low power(b) More noise(c) Unpredictable path(d) Not economical |

Answer» Right answer is (c) Unpredictable path The best I can explain: The sky waves makes some types of long range communication possible, but is of less value to navigation system because it’s transmission path is unpredictable. A rough location where the sky waves might get reflected can be determined by Snell’s law. |
