The image 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.)

Remember that the period of a sinusoidal function is the vertical distance between the t-axis and one of the extreme points. From the graph we can infer that the period of the function is 4.5.

Also, the amplitude is the distance between two consecutive maximum or two consecutive minimum points. From the graph we can infer that the amplitude of the function is 0.05 seconds.

We can conclude that the correct answer is: 0.05 seconds; 4.5
