The speed of water waves in the sea, which have wavelength 300 m is 21 m/s.
What is speed?
Speed is the distance travelled by an object in per unit time.
Given that, the wavelength of the waves is 300 m
The frequency of the waves is 0.07 hz
To find the speed
By the formula of speed
Speed = frequency × Wavelength
Putting the value in the equation
Speed = 300 × 0.07 = 21
Thus, the speed of these waves is 21 m/s
