Physics Why are we able to hear short wave broadcasts better than long wave broadcasts ? Short waves are unaffected by atmospheric disturbances. Short wave broadcasts are made by nearby radio stations. Short waves are more energetic than long waves. By convention, short waves are meant for long distances, whereas long waves are reserved for short distances. Short waves are unaffected by atmospheric disturbances.

Physics Which one of the following statements with regard to Jet stream, an upper level tropospheric wave, is not correct? Jet streams are typically continuous over long distances. In summer, the polar front jet achieves its maximum force. It follows the wave path near the tropopause at elevations of 8 km to 15 km. It is narrow band of high-velocity wind.
