By means of a ripple tank, a student was able to generate series of transverse waves by varying the frequency of the dipper and all the waves so generated covered a distance of 0.80m in 0.2seconds.determine the speed,v of the waves. what does the slope of the graph represents , and determine the slope.
Answer
To determine the speed (v) of the waves, we can use the formula:
v = distance / time
Given:
Distance (d) = 0.80 m
Time (t) = 0.2 s
Substituting the values into the formula, we get:
v = 0.80 m / 0.2 s
v = 4 m/s
Therefore, the speed (v) of the waves is 4 m/s.
Next, let's discuss the graph. We are given that the waves were generated by varying the frequency of the dipper. The frequency (f) of a wave is the number of complete waves passing a point in one second. The frequency is typically measured in hertz (Hz).
The graph is most likely a graph showing the relationship between the frequency of the dipper and some other variable, like the wavelength or the period. The slope of this graph represents the change in the dependent variable (e.g., wavelength) per unit change in the independent variable (e.g., frequency). It shows how these two variables are related.
To determine the slope of the graph, you would need to have the equation of the line or two points on the graph. Without that information, I'm sorry, but I'm unable to provide a specific value for the slope.
To determine the speed, v, of the waves, we can use the formula:
v = λf
Where v is the speed of the waves, λ is the wavelength, and f is the frequency.
To find the slope of the graph, we need to plot the distance covered by the waves (y-axis) against the time taken (x-axis). Since the distance covered is 0.80m and the time is 0.2 seconds, we can plot these points on a graph. The slope of this graph represents the speed of the waves.
To calculate the slope, we can use the formula:
slope = (change in y) / (change in x)
In this case, the change in y is 0.80m (distance) and the change in x is 0.2s (time). Therefore, the slope can be calculated as:
slope = (0.80m) / (0.2s) = 4 m/s
So, the speed of the waves is 4 m/s, and the slope of the graph represents this speed.
