Waves propagate along a stretched string at a speed of 6.9 m/s. The end of the string vibrates up and down once every 3.6 s. What is the wavelength of the waves traveling
along the string?

24.64m

Explanation:

The formula for  calculating the wavelength is expressed as;

wavelength = Speed/frequency

Given

Speed = 6.9m/s

Frequency = 1/Period

Frequency = 1/3.6

Frequency = 0.28Hz

Get the wavelength

wavelength = 6.9/0.28

wavelength = 24.64m

Hence the wavelength of the waves traveling  along the string is 24.64m

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.
