To determine the speed of a transverse pulse propagated through a stretched string.
A pulse is small disturbance through medium lasts for short time.
Transverse pulse – Particles of medium moves perpendicular to the direction of motion of pulse.
We can observe pulse in long stretched string. The pulse reflects when it reaches fixed boundary.
If a pulse travels through string, we can use equation
To find velocity of a pulse through string
l-length of string
T-Time period of pulse
Speed of pulse is different for different string length. Speed of pulse may be different for same length.
Factors affecting speed of pulse
Speed of a pulse depends upon the tension and mass per unit length of the string
T-Tension on the string
μ-mass per unit length of the string.
