Question

A Fisherman in a row boat notices that one wave crest passes his fishing line ever 5 seconds. He estimates the distance between the crests to be 1.5 meters and that the crests of the waves are about .5 meters above the troughs. Using this data, determining the amplitude and speed of the waves.

Answer 1

It should be 0.25. I don't really know how to get that from the equation (Amplitude=distance/frequency), but since the problem said that "the crests of the waves are about .5 meters above the troughs." I divided that by two.

Answer 2

I have that question in my science class, searching up quizlets other people made gives u the answer

Answer 3

I have that problem and I am solving it and so far I got the amplitude which is 0.2

Answer 4

I got 7.5 for the speed and 0.2 for the ampitude.

Answer 5

i don't get this miss bunch

Answer 6

To determine the amplitude and speed of the waves, we can use the formula for wave speed, which is given by:

Wave speed (v) = frequency (f) x wavelength (λ)

First, let's determine the frequency of the waves. The frequency (f) is the number of wave crests passing a point in a given time. In this case, the fisherman notices that one wave crest passes his fishing line every 5 seconds.

So, frequency (f) = 1 wave crest / 5 seconds = 1/5 Hz

Next, let's determine the wavelength (λ). The wavelength is the distance between successive crests or troughs of the wave. The fisherman estimates the distance between the crests to be 1.5 meters.

Therefore, wavelength (λ) = 1.5 meters

Now, we can use the formula for wave speed to find the speed (v) of the waves:

v = f x λ

Substituting the values we found:

v = (1/5 Hz) x (1.5 meters)

v = 0.3 meters/second

Therefore, the speed of the waves is 0.3 meters per second.

Now, let's determine the amplitude of the waves. The amplitude is the maximum displacement of the wave from its equilibrium position. The fisherman estimates that the crests of the waves are about 0.5 meters above the troughs.

Therefore, the amplitude of the waves is 0.5 meters.

In summary, the amplitude of the waves is 0.5 meters and the speed of the waves is 0.3 meters per second.
