Question

Quizplus · Accepted Answer

Television signals, like other types of radio frequency signals, can sometimes be reflected by the ionosphere (a layer of the Earth's upper atmosphere) under certain conditions, but they primarily travel in straight lines and do not follow the curvature of the Earth. This is why television broadcasting and reception are generally limited to line-of-sight distances.
