Question

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?

Answer 1

24.64m

Step-by-step 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
