1.	In communication with help of antenna if the height is doubled, then the range covered which was initially r would become what?(a) √2r(b) 3r(c) 4r(d) 5rThis question was addressed to me in a job interview.Asked question is from Communication Systems in portion Communication Systems of Physics – Class 12
Answer» The correct ANSWER is (a) √2r Explanation: Initial range, r = √2Rh. When the HEIGHT of the antenna is DOUBLED, r’ = √2R × 2H = √2r.
