How does damping affect the speed of a wave?

Damping of a wave lowers the amplitude of a wave, PE and KE decrease but frequency remains the same.

What effect does tension have on wavelength?

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

What is the relationship between tension and wavelength?

adnan, The exact relationship between frequency and wavelength is f = c/λ. When you change the tension on the string, you are changing the wave speed (c) and frequency, but not the wavelength. Specifically, as the frequency goes down, the speed goes down by the same factor, and so the wavelength doesn’t change.

How does wave speed depend on tension?

The speed of a wave on a string depends on the square root of the tension divided by the mass per length, the linear density. In general, the speed of a wave through a medium depends on the elastic property of the medium and the inertial property of the medium.

Does damping affect the wavelength?

wave speed is proportional to the square root of tension & thus wavelength is also proportional to the sqrt of tension. However, damping doesn’t affect wavelength,frequency & wave speed. It just decreases the amplitude of the wave.

What is the effect of damping on the waves?

For things like pendulum, spring-mass, LCR circuit, the effect of damping is to slow the oscillation and therefore increase the period. So the generated waves have longer period and lower frequency as well as the obvious decreasing amplitude.

Is tension directly proportional to speed?

From equation (2) we see that the square of the wave velocity is, in turn, directly proportional to the tension, since the linear density μ is constant in this experiment. It follows that the square of the wavelength should be directly proportional to the tension.

How does increasing tension increase wave speed?

Increasing tension lengthens the wavelength, reduces the amplitude, increases the frequency, and therefore an increase in the speed.

Does wavelength decrease with tension?

Increasing the tension increases the speed and the frequency. The wavelength is unchanged, being determined by the length of the string.

Why does increasing 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.

How does increasing damping change the wave?

Damping; it decreases the amplitude of the wave as it propagates. Damping; it increases the amplitude of the wave as it propagates.

What is the effect of damping?

Damping makes the vibration regular and smaller compared to undamped oscillation. Structural Yielding: The energy absorbed by yielding parts of a structure can significantly reduce vibrations in an earthquake. Severe earthquakes cause structural elements to give way, adding a significant amount of damping.

How does tension affect the frequency of a wave?

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.

What is the difference between damping and frequency and amplitude?

Frequency; it decreases the amplitude of the wave as it propagates. Frequency; it increases the amplitude of the wave as it propagates. Damping; it decreases the amplitude of the wave as it propagates. Damping; it increases the amplitude of the wave as it propagates.

How does damping affect the speed of wave packets?

The higher it is, the more damping there is. As the damping increases, the phase speed decreases, but the group speed actually increases. So your wave packets will propagate faster down a string in water than the same string in air! The extra damping in water makes the wave packets travel faster—not slower.

What is the effect of damping on phase speed?

The higher it is, the more damping there is. As the damping increases, the phase speed decreases, but the group speed actually increases. So your wave packets will propagate faster down a string in water than the same string in air!
