Question

A tuning fork is struck and produces a sound. The wavelength of this
sound is 2.5 m and the period of this sound is 0.25 s. Find the
frequency of the sound wave and the speed of the wave.

Answer 1

Answer:

Speed= 10meters per second, Frequency = 4hz

Explanation:

First we need to find the frequency of the wave. The formula for frequency is: f (frequency) = 1 / T (period). This means we need to convert the period into seconds and then use it as a denominator with one on the numerator.

Since the period is 0.25,

1/0.25= 4hz

Now, we just need to multiply the frequency with the wavelength

4hzx2.5= 10

= 10 meters per second
