# What is the speed of a wave on the string?

• Efast
In summary, the speed of the wave on the string is 39.6 m/s. The equation used was v = √ T / (m/L), where T is the tension in the string, m is the mass of the string, and L is the length of the string. There may be a mistake in the given or answer, as the correct answer should be 39.62 m/s.

## Homework Statement

The tension in the string is 90N; the string is 60cm long and has a weight of 34.44g. What is the speed of the wave on the string?

v = √ T / (m/L)

## The Attempt at a Solution

v = √ 90N / (0.0344kg/0.6m)
v = 39.6 m/s

Huh? This looks like it should be pretty simple, plug in and get the answers...
What am I doing wrong, i need one more digit!??

Your solution looks correct to me.

I once had a physics teacher who would dig through the questions and solutions so he could assign all of the ones that were wrong. A lot to be learned that way (like which professor never to sign up for again!)

The answer is 39.62 m/s, there must be a mistake in the given or answer! check you prof.

## What is the speed of a wave on the string?

The speed of a wave on a string is determined by the tension of the string and the mass per unit length of the string.

## How is the speed of a wave on a string calculated?

The speed of a wave on a string can be calculated using the equation v = √(T/μ), where v is the speed, T is the tension, and μ is the mass per unit length.

## What factors affect the speed of a wave on a string?

The speed of a wave on a string is affected by the tension of the string, the mass per unit length of the string, and the wavelength of the wave.

## What is the relationship between the wavelength and speed of a wave on a string?

The wavelength and speed of a wave on a string are inversely proportional. This means that as the wavelength increases, the speed decreases and vice versa.

## Can the speed of a wave on a string be greater than the speed of light?

No, the speed of a wave on a string is limited by the properties of the string and cannot exceed the speed of light, which is the maximum speed at which any object can travel in the universe.
