Assertion : Television signals are received through sky-wave propagation Reason : The ionosphere reflects eletro magnetic waves of frequencies greater than a certain critical frequency.

Statement-1: Television signals are propagated through sky waves. Statement-2 : Television signals have frequency in the 100-200 MHz range.

Statement-1 : Electromagnetic waves with frequencies smaller than the critical frequency of ionosphere cannot be used for communications using sky wave propagation. Statement-2: The refractive index of the ionosphere becomes very high for frequencies higher than the critical frequency.
