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

The speed of a wave on a string depends on the linear density of the string and the tension in the string. The linear density is mass per unit length of the string. In general, the speed of a wave depends on the square root of the ratio of the elastic property to the inertial property of the medium.

### How do you find the speed of a wave in a string?

The speed of a wave on a string can be found by multiplying the wavelength by the frequency or by dividing the wavelength by the period.

**What factors do not affect the speed of a wave?**

The amplitude of a wave does not affect the speed at which the wave travels. Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.

**Does tension increase wave speed?**

The fundamental wavelength is fixed by the length of the string. Increasing the tension increases the wave speed so the frequency increases.

## What is damping of a wave?

damped wave [¦dampt ‚wāv] (physics) A wave whose amplitude drops exponentially with distance because of energy losses which are proportional to the square of the amplitude. A wave in which the amplitudes of successive cycles progressively diminish at the source.

### Does increasing frequency increase speed?

When frequency increases, speed increases and vice versa.

**Why does tension increase wave speed?**

Tension determines the vertical force (perpendicular to wave motion) on molecules of string and hence determines the speed of perpendicular motion. Faster the perpendicular motion, faster the wave has passed by. Increasing the string tension effectively reduces the remaining elastic capacity.

**Why does increasing tension increase wave speed?**

## Does higher frequency mean faster speed?

Frequency is expressed in units of cycles per unit time. Although frequency is a measurement of rate of movement, it is not identical to velocity. Comparing two waves of the same wavelength, a higher frequency is associated with faster movement.

### What is the wave speed and tension in the string?

The speed of a wave pulse traveling along a string or wire is determined by knowing its mass per unit length and its tension. In this formula, the ratio mass/length is read mass per unit length and represents the linear mass density of the string. This quantity is measured in kilograms/meter.

**How does the string length affect wave speed?**

Increasing the tension on a string increases the speed of a wave, which increases the frequency (for a given length). Pressing the finger at different places changes the length of string, which changes the wavelength of standing wave, affecting the frequency. (Smaller lengths of string result in shorter wavelength and thus higher frequency.)

**What is the wave speed on this string?**

The speed of a wave on a string can be found by multiplying the wavelength by the frequency or by dividing the wavelength by the period. The type of wave that occurs in a string is called a transverse wave.

## What are the SI units for a wave speed?

The SI unit of particle velocity is the metre per second (m/s). In many cases this is a longitudinal wave of pressure as with sound, but it can also be a transverse wave as with the vibration of a taut string.
