Una superficie de agua se golpea con una regla cada 0,2 segundos. Si la longitud de onda de la onda que se produce
es 3,5 cm, calcula:
a. La frecuencia de la onda.
b. La velocidad de propagación de la onda.

For this case we have:

A surface of water is hit with a ruler every 0.2 seconds. If the wavelength of the wave that occurs is 3.5 cm, calculate:

a. The frequency of the wave.

b. The velocity of wave propagation.

By definition, we have that the velocity of propagation of the wave is given by:

Where:

w: is the wavelength

f: It is the frequency

On the other hand, we can find the frequency:

Thus, the velocity of propagation of the wave is:

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

think its the third option
