Wavelength is a measure of the distance between two crests or two troughs of a wave. The greater the wavelength, the more energy a wave has. AM radio stations have a big wavelength. You might have tuned the radio dial at night and heard stations that were far away and unable to be heard during the daytime.
The Philadelphia Flyers have won two Stanley Cups. They won in the  1973-1974 and the 1974-1975 seasons. They have 8 conference  championships.
After 1947, the Cup became the de jure NHL championship prize. From 1914 to the end of the 2016 season, the trophy has been won 98 times. 23 different teams have won the cup, 18 of which are still active in the NHL. Prior to that, the challenge cup was held by nine different teams. The Montreal Canadiens have won the Stanley Cup 24 times and made the finals an additional ten times. There were two years when the Stanley Cup was not awarded: 1919, because of the Spanish flu epidemic, and 2005, because of the NHL lockout.
