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