===About Wave Speed===
: [[Wave Speed]] is measured in [[metres per second]].
: The '''wave speed''' states how quickly [[energy]] and [[information]] can be transferred by a [[wave]].
 
===Equation===
====Equation 1====
<math>v = \frac{x}{t}</math>
 
Where:
 
v = '''Wave Speed'''
 
x = distance traveled
 
t = time taken to travel
 
====Equation 2====
 
<math>v = f \lambda</math>
 
<math>v = f \times \lambda</math>
 
Where:
 
v = '''Wave Speed'''
 
f = [[frequency]] of the [[wave]]
 
λ = [[wavelength]] of the [[wave]]
 
==Key Stage 4==
===Meaning===
[[Wave Speed]] is how quickly a [[wave]] travels through a [[medium]].
 
===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 '''wave speed''' states how quickly [[energy]] and [[information]] can be transferred by a [[wave]].
====Equation 1====
:<math>v = \frac{x}{t}</math>
 
Where:
: v = '''Wave Speed''': x = distance traveled: t = time taken to travel
====Equation 2====
:<math>v = f \lambda</math>:<math>v = f \times \lambda</math>
Where:
: v = '''Wave Speed''': f = [[frequency]] of the [[wave]]: λ = [[wavelength]] of the [[wave]] ===Example Calculations==={| class="wikitable"| style="height:20px; width:300px; text-align:center;" |Question| style="height:20px; width:300px; text-align:center;" |Question|-| style="height:20px; width:300px; text-align:left;" |'''1.
