1.	Distance at which a sky wave is received back on earth ________ with an angle of incidence.(a) increases(b) decreases(c) can be increase or decrease(d) can neither be increase or decreaseI have been asked this question by my college professor while I was bunking the class.This question is from Costas Loop topic in portion Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» The correct CHOICE is (B) decreases The best I can EXPLAIN: The distance at which a SKY wave is RECEIVED back on earth is inversely proportional to the angle of incidence. Thus, the distance at which a sky wave is received back on earth decreases with an angle of incidence.
