Hi there! Can you take couple minutes to help me out with a sound wave question please? Thanks!
1 Answer
a.
b.
c.
Explanation:
a. The period is how long the cycle of a wave is, the unit length between two adjacent peaks/troughs.
So, we want to know what values for
So, we know that a peak will occur when
The unit length between two peaks is the period and is 3.
For period I say it is unit length, which is the number of whole squares on the graph.
b. The amplitude is the highest point reached by the graph from the equilibrium point. This can be found using the equation as the maximum value for
c. The midline is the line that runs through the equilibrium point of the graph, where the "average"
Since the graph has a maximum of 1 and a minimum of -1, the midline is found by doing
Also, as the general equation is in the form of
