Topic 1: Transverse pulses on a string or spring
Pulse
A single disturbance transplanted in a medium.
When the particles of the medium Hand makes up-
move perpendicular to the down movement
direction of motion of the pulse
Direction of motion
Transverse pulse
Direction of disturbance
distance
speed =
time
pulse speed
Position
amplitude
displacement of particles
position of rest
Distance
Pulse length
CONCEPTS AND DEFINITIONS
The maximum displacement (disturbance) of a particle in a medium from
Amplitude
its position of rest (equilibrium position).
Medium Substance or material along which the pulse moves.
Pulse A single disturbance that moves in a medium from one point to another.
Pulse length Distance from the starting point to the endpoint of a pulse.
Position of rest The position of the medium (rope or spring) when no disturbance moves
(equilibrium) through it.
Speed The distance travelled per time. / Rate of change of distance.
A single disturbance in a medium perpendicular to the direction of motion
Transverse pulse
of the pulse.

Experiment 1: Generation of a transverse pulse
Aim: To generate a transverse pulse in a spring or rope
Apparatus
• Slinky (spiral spring) or strong rope
• Piece of string or ribbon
Method
1. Fasten the ribbon to one of the spirals of the slinky. Hold the slinky on the floor.
2. Let a friend hold the other end of the spring tightly or fasten it to an object.
3. Pull the free end of the spring and quickly move it to one side and back to its original position.
Observe the motion of the ribbon.
Results and Questions
1. Sketch the pulse observed in the spring. On the sketch indicate the following:
Position of rest, direction of movement of pulse, direction of displacement (disturbance)
2. In which direction did the pulse travel?
3. In which direction is the disturbance?
4. The ribbon represents a particle on the spring. Does the ribbon move in the direction of the
pulse or in the direction of the disturbance?
Activity 1.1: Classwork/Homework
1. Define each of the following terms:
1.1 Pulse
1.2 Transverse pulse
1.3 Position of rest
1.4 Amplitude
2. A learner generates a transverse pulse in a slinky.
2.1 How must the learner move his hand to generate a transverse pulse?
2.2 How does the direction of motion of the coils of the spring compare to the direction of
motion of the pulse?
2.3 Explain how the motion of the coils of the spring allows the pulse to propagate.
2.4 Sketch the transverse pulse. On the sketch indicate, using labels, the amplitude,
position of rest and pulse length.
3. A pulse has a speed of 0,5 m·s-1. Calculate the time taken for the pulse to move 25 m.
