1 answer is correct. Easy Official question catalogue

1. A The waves travel as ground waves along the surface of Earth and, therefore, also penetrate into valleys, hence they cannot be influenced by topographical obstacles
2. B The waves are reflected by the ionosphere at an altitude of about 100 km and return to the Earth's surface as sky waves
3. C Similar to short waves but they are unaffected by atmospheric disturbances
4. D Similar to light, i.e. "quasi optically"
