You are holding a string tied to a lamp post 15 m away. You pull the string so that it has a tension of 1.5 N and a mass density of 0.0045 kg/m. You shake the end of the string at 4 Hz. What is the wavelength of the wave you generate in m

Respuesta :

Answer:

Explanation:

Given that

L= 15 m

T= 1.5 N

μ =0.0045 kg/m

f= 4 Hz

We know that

Velocity in string V is given as

[tex]V=\sqrt{\frac{T}{\mu}}[/tex]

Now putting the values in the above equation we get

[tex]V=\sqrt{\frac{1.5}{0.0045}}=18.25\ m/s[/tex]

We know that

V= f λ

[tex]\lambda =\frac{V}{f}[/tex]

[tex]\lambda =\frac{18.25}{4}=4.5 m[/tex]
