The screen below shows the graph of a sound recorded on an oscilloscope. What are the period and the amplitude? (Each unit on the t-axis equals 0.01 seconds.)
Graph 5• The t axis extends from 0 to 0.18.
• The f of t axis extends from negative 5 to 5.
• The graph begins at about 0 comma 0.7, then increases to 0.012 comma 4.5, and decreases, crossing the x-axis at approximately 0.024 to about 0.037 comma negative 4.4.
• From this point, the graph increases, crossing the x-axis at 0.05, to about 0.062 comma 4.5.
• The pattern continues ending at approximately 0.18 comma negative 2.5.
