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.
Prior to 1977 only players who had completed the Stanley Cup playoffs were eligible. Today, players appearing in 41 regular-season games or one Stanley Cup Final game for the championship team have their names engraved on the Cup. The NHL makes exceptions for players who do not meet the standard because of injury or other extenuating circumstances.
