The number of Waves can be Two, Three or more. The spring rate is proportional to the number of waves raised to the fourth power.

Wave Washers are generally preferred as cushion / cushion spacers between parts on shafts or to take up the probable deviation in assembled parts. These are positioned underneath a Nut, an Axle Bearing, or a Joint, to reduce friction, avoid leekage, isolate, stop loosening or distribute pressure.
