Periodic waves spread out over the surface of a lake where two women, Jenny and Melissa, are fishing in separate boats 46 meters

Tatiana [17]

Answer:

The wavelength of the water is $\lambda = 10.22 m$

Explanation:

From the question awe are told that

The distance between the two boats are 46 m

Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as

Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)

= 4.5

Now the wavelength of the water is $\lambda = \frac{Distance }{Number \ of \ division }$

$= \frac{46}{4.5} =10.22m$

How are velocity, wavelength, and frequency related

Readme [11.4K]

Answer:

The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ. The wave frequency and the period are inversely related to one another.
