Frequency
Explanation:
Wave frequency is the number of waves that pass a fixed point in a given amount of time.
Wave speed is the speed at which a wave travels.
Let the wave speed be [tex]v[/tex]
Let the wave frequency be [tex]f[/tex]
Let the wave length be [tex]l[/tex]
The wave speed,frequency and wave length are related by the equation [tex]v=f\times l[/tex].
When [tex]v[/tex] increases,[tex]f[/tex] increases on the other side to maintain equality when no other property is changing.
