The speed of the wave on the stretched string is 1.41 m/s.
To calculate the speed of the wave, we use the formula below.
Formula:
- V = √(TL/m).............. Equation 1
Where:
- V = speed of the string
- T = Tension
- L = Length of the string
- m = mass of the string.
From the question,
Given:
- T = 20 N
- L = 0.25 m
- m = 2.5 kg
Substitute these values into the equation 1
- V = √(20×0.25/2.5)
- V = √(2)
- V = 1.41 m/s
Hence, the speed of the wave on the stretched string is 1.41 m/s.
