Television signals lies in region of 40 MHz to 900 MHz, so these are not reflected by ionosphere and can be communicated by using a satellite only. It is because, ionosphere reflects electromagnetic wave of frequencies in the range of 3 MHz to 30 MHz. Hence, Assertion is false but Reason is true.

Q. Assertion ( A ) : Television signals are received through sky- wave propagation Reason(R): The iono sphere reflects electromagnetic waves of frequencies in therange (3−30)MHz

(A) is true, (R) is rue and (R) is the correct explanation for (A)

(A) is true, (R) is true but (R) is not the correct explanation for (A)

(A) is true but (R) is false

(A) is false but (R) is true
