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° or $\frac{pi}{6}$

Answer

Explanation:

Step1: Determine the amplitude

The amplitude is the maximum displacement from the equilibrium position. Counting the vertical squares from the equilibrium (x - axis) to the peak. If each vertical square represents 5, and assume the peak is 2 squares above the equilibrium. Then the amplitude $A = 2\times5=10$.

Step2: Determine the period

The period is the horizontal length for one complete cycle. Counting the horizontal squares for one full - cycle. If each horizontal square represents $30^{\circ}$ or $\frac{\pi}{6}$ radians, and assume one full - cycle is 6 squares long. Then the period $T = 6\times30^{\circ}=180^{\circ}$ or $T = 6\times\frac{\pi}{6}=\pi$ radians.

Answer:

Amplitude: 10; Period: $180^{\circ}$ or $\pi$ radians
