Question

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

• A. (A) is true, (R) is rue and (R) is the correct explanation for (A)
• B. (A) is true, (R) is true but (R) is not the correct explanation for (A)
• C. (A) is true but (R) is false
• D. (A) is false but (R) is true

Answer 1

Answer: (D)

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.
