A famous example from the Hallelujah Chorus. The blue notes are the cadence itself.
A plagal cadence is used to end and resolve a musical phrase, and is created by using a IV - I chord movement. As well as being a much-loved cadence in pop music, it shows up a great deal in church music, usually as part of the "amen" in a hymn.
