The first harmonic of a string tied down at both ends has a frequency of 26 Hz. If the length of the string is 0.83 m, what is the speed of waves on the string?

the speed of the wave on the string is 43.16 m/s

Explanation:

Given;

first harmonic of the wave formed by the string, f₀ = 26 Hz

length of the string, L = 0.83 m

The wavelength for first harmonic of the wave is calculated as;

L = N > N

L = λ₀/2

λ₀ = 2L

The speed of the wave on the string is calculated as follows;

v = f₀λ₀

v = f₀ x 2L

v = 26 x 2 x 0.83

v = 43.16 m/s

Therefore, the speed of the wave on the string is 43.16 m/s
