Two waves A and B of frequencies 2 MHz and 3 MHz, respectively are beamed in the same direction for communication via skywave. Which one of these is likely to travel a longer distance in the ionosphere before suffering total internal reflection?
The refractive Index Increases with Increase In frequency which Implies that for higher frequency waves, angle of refraction is less. I.e.. bending Is less. Hence, the condition of total internal reflection is attained after travelling larger distance (by 3MHz wave).
