Term
Definition
What is a medium?
A medium is the substance or material through which a pulse moves.
Define a pulse.
A pulse is a single disturbance that moves through a medium.
What characterizes a transverse pulse?
In a transverse pulse, the displacement of particles of the medium is perpendicular to the direction of movement of the pulse.
What is amplitude in the context of a pulse?
The amplitude of a pulse is the maximum disturbance from its rest (equilibrium) position.
How is pulse speed defined?
Pulse speed is the distance a pulse travels per unit time, calculated as v=D/t.
What factors affect pulse speed?
Pulse speed depends on the properties of the medium, not on the amplitude or pulse length.

Explain the principle of superposition.
The principle of superposition states that when two disturbances occupy the same space at the same time, the resulting disturbance is the sum of the two disturbances.
What is constructive interference?
Constructive interference occurs when two pulses meet to create a larger pulse, such as two crests or two troughs meeting.
Describe destructive interference.
Destructive interference is when two pulses meet, resulting in a smaller pulse.
What are the units for amplitude and pulse speed?
Amplitude is measured in metres (m), and pulse speed is measured in metres per second (m⋅s−1).
