Question

Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : Television signals are received through sky-wave propagation.
Reason : The ionosphere reflects electromagnetic waves of frequencies greater than a certain critical frequency.

Options:

A . If both assertion and reason are true and the reason is the correct explanation of the assertion.

B . If both assertion and reason are true but reason is not the correct explanation of the assertion.

C . If assertion is true but reason is false.

D . If the assertion and reason both are false.

E . If assertion is false but reason is true.

Answer: Option D
:
D
TV signals (frequency greater than 30 MHz) cannot be propagated through sky wave propagation.
Above critical frequency, an electromagnetic wave penetratates the ionosphere and is not reflected by it.
