Find the period

Part 2 of 2 Points: 0.5 of Pure sounds produce single sine waves on an oscilloscope. K Q Find the amplitude and period of the sine wave graph. On the vertical scale, each square represents .5; on the Q horizontal scale, each square represents 30 or The amplitude is 2 (Simplify your answer. Type an exact answer, using x as needed. Use integers or fractions for ary numbers in the expression.) The period is (Simplify your answer. Type an exact answer, using a as needed. Use integers or fraction for any numbers in the expression.)
