KQ.R2, Why should broadensting programs we, different frequenctes?, , Ans: If broadcasting programs fun on same, frequency, then the information carried by, these waves Will get mixed up with each other., Honce, different broadcasting programs should, run on different frequencies., , KQ.83. Give reasons for the following:, , i. Long distance radio broadcast uses short, wave bands., , ii. Satellites are used for long distance a, transmission., , 1 Long distance radio broadcast uses short waye, bands because electromagnetic waves only in, the frequency range of short wave bands only, , . are reflected by the ionosphere., , 7) a. Itismecessaly to use satellites for long, distance TV transmissions because, television signals are of high, frequencies and high energies. Thus,, these signals are not reflected by the, ionosphere. }, , b. Hence, satellites are helpful in long, distance TV transmission.
