Question

A string of a guitar 1.3 m long vibrates with 4 nodes, 2 of them at the two ends. Find the wavelength & speed of the wave in the string if it vibrates at 500 Hz. (lamda=0.866m, v= 433ms)​

Answer 1

Given,

A string of a guitar 1.3 m long vibrates with 4 nodes, 2 of them at the two ends. Find the wavelength & speed of the wave in the string if it vibrates at 500 Hz. (lamda=0.866m, v= 433ms)

So,

Number of nodes = 4

Number of loops = 3

Length of the string = L = 1.3 m

Frequency = f3 = 500 Hz

And

Wavelength = λ3 =?

Speed of the wave = v =?

Now,

$\mathtt{λn = \frac{2 \times 1.3}{3} } \\ \\ \mathtt{ = \frac{2.6}{3} } \\ \\ \mathtt{ = 0.866 \: m \: \: \:ans }$

And,

V = 500 × 0.866 = 433 ms-1 ans
