Answer:
As Per Provided Information
Velocity of wave v is 10m/s
These ocean wave passes a stationary point every 5 s ( It's time period)
First we calculate the frequency of ocean wave .
Using Formulae
[tex] \blue{\boxed{\bf \: \nu = \cfrac{1}{v}}}[/tex]
here
v is the velocity of wave .
[tex]\sf\longrightarrow \nu \: = \cfrac{1}{10} \\ \\ \\ \sf\longrightarrow \nu \: = 0.1Hz[/tex]
Now calculating the wavelength of the wave .
Using Formulae
[tex] \boxed{ \bf \lambda = \cfrac{v}{ \nu}}[/tex]
Substituting the value and we obtain
[tex] \sf \longrightarrow \lambda \: = \cfrac{10}{0.1} \\ \\ \\ \sf \longrightarrow \lambda \: = \cancel\cfrac{10}{0.1} \\ \\ \\ \sf \longrightarrow \lambda \: =100m[/tex]
Therefore,
- Wavelength of the wave is 100 metres.
