 ===About Wave Speed===
 : '''Wave speed''' is a [[scalar]] because it has [[magnitude]] only.
-: The [[SI Unit]] of [[Wave Speed|wave speed]] is [[metres per second]].
+: The [[SI Unit]] of [[Wave Speed|wave speed]] is [[Metres per Second|metres per second]].
 : The '''wave speed''' states how quickly [[energy]] and [[information]] can be transferred by a [[wave]].
 : '''Wave speed''' can change depending on the [[medium]] the [[wave]] is travelling through.
