If an ocean wave passes a stationary point every 5 s and has a velocity of 10 m/s, what is the wavelength of the wave

Sagot :

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.
