Question

What quantities determine how quickly a wave travels along a string? Choose all that apply..a)Mass of the stringb)Length of the stringc)Tension in the stringd)Linear density of the string

Answer 1

Answer:

a)Mass of the string

b)Length of the string

c)Tension in the string

d)Linear density of the string

Explanation:

The speed of a wave on a string is given by:

$v=\sqrt{\frac{T}{m/L}}$

where

T is the tension in the string

m is the mass of the string

L is the length of the string

m/L is the linear density of the string

Looking at the formula, we notice that the speed of the wave, v, depends on all the following quantities:

a)Mass of the string

b)Length of the string

c)Tension in the string

d)Linear density of the string
