Consider a string tied toward one side and you are moving the flip side in your grasp. The speed of a wave pulse traveling along a string or wire is determined by knowing its mass per unit length and its tension.ALFVEN VELOCITY. For the solar wind waves travelling between the sun and earth, they behave like waves on a string in tension. As you say, this formula implies that the speed of a transverse wave on a stretched string doesnt depend on the frequency, because we know that neither T nor mu has any dependence on frequency. Since the wave velocity is given by.This shows a resonant standing wave on a string. It is driven by a vibrator at 120 Hz. For strings of finite stiffness, the harmonic frequencies will depart progressively from the mathematical harmonics.

Why in a sinusoidal wave the velocity of a particle on the string is not the same as the velocity of the wave along the string? The velocity of light is 3X108 m /s. how can this velocity be applied to both wave and particle situation? The string will also vibrate at all harmonics of the fundamental. Each of these harmonics will form a standing wave on the string.The velocity of a traveling wave in a stretched string is determined by the tension and the mass per unit length of the string. Vibrations and Waves. 13. The speed of the transverse wave is measuring how fast the wave disturbance moves along the cord.reduced to 2/3 of its current value, and the velocity of waves on the string is not changed, then the. new frequency will be. Peaks and valleys coincide.
