Key Stage 3
Meaning
Wave Speed is how quickly a wave travels through a medium.
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
\(v = \frac{x}{t}\)
Where:
v = Wave Speed
x = distance traveled
t = time taken to travel
Equation 2
\(v = f \lambda\)
\(v = f \times \lambda\)
Where:
v = Wave Speed
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 is metres per second.
- The wave speed states how quickly energy and information can be transferred by a wave.
Equation
Equation 1
\[v = \frac{x}{t}\]
Where:
v = Wave Speed
x = distance traveled
t = time taken to travel
Equation 2
\(v = f \lambda\)
Where:
v = Wave Speed
λ = wavelength of the wave
