Periodic waves spread out over the surface of a lake where two women, Jenny and Melissa, are fishing in separate boats 46 meters apart. Each woman's boat bobs up and down 26/min. At a time when Jenny's boat is at a crest, Melissa's boat is at its lowest point, and there are 4 additional crests between them. Calculate the wavelength of these water waves.

The wavelength of the water is

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

it is called kinetic energy

total distance/total time

(85 + 82)/(5+3)
