1.	Identify a suitable frequency for skywave propagation.(a) Upto 2 MHz(b) From 2 MHz to 30 MHz(c) From 2 MHz to 50 MHz(d) From 2 MHz to 80 MHzThe question was posed to me during an online interview.My doubt stems from Communication Systems topic in portion Communication Systems of Physics – Class 12
Answer» Correct answer is (B) From 2 MHZ to 30 MHz For explanation I would say: Skywave propagation is USEFUL for radiowaves of frequency from 2 MHz to 30 MHz. Frequencies that are higher than 30 MHz cannot be reflected by the IONOSPHERE.
