Given below are two statements : one is labeled as Assertion A and the other is labeled as Reason R.
In the light of the above statements, choose the correct answer from the options given below.
| Assertion A : | Communication techniques which are using much higher frequencies like TV signal broadcast, can not be received beyond the line-of-sight. |
| Reason R : | Radio waves used for radio broadcast which are in the below critical frequency range, receive reflection from the ionosphere and can be received by the receiving antenna. |
Official answer
(1)
Both $\displaystyle \mathbf{A}$ and $\displaystyle \mathbf{R}$ are true and $\displaystyle \mathbf{R}$ is the correct explanation of $\displaystyle \mathbf{A}$.
