Question

Use a sine function to graph a sound wave with period of 0.002 seconds and an amplitude of 5 cm. Find the frequency in hertz for the sound wave.

Answer 1

500Hertz

Explanation:

Using the formula for calculating frequency in terms of period expressed as;

f = 1/T

f is the frequency

T is the period

Given

T = 0.002seconds

Frequency f = 1/0.002

Frequency f = 500Hertz

Hence the frequency in hertz for the sound wave is 500Hertz
