Pure sounds produce single sine waves on an oscilloscope Fin

Pure sounds produce single sine waves on an oscilloscope. Find the amplitude and period of the sine wave graph. On the vertical scale, each square represents .5; on the horizontal scale, each square represents 30 degree pi/6. The amplitude is (Simplify your answer. Type an exact answer, using pi as needed. Use integers or fractions for any numbers in

Solution

Given

on vertical scale each square represents 5

the peak of sine wave touches the 8 line above the x-axis,therefor amplitude =5*8=40

on horizantal axis each square represents 30 degrees

the sine wave completes in 8 boxes,therefore the peroid =8*30=240 degrees
