Pulses: Amplitude and Length (Grade 10 NSC Matric Physical Sciences): Flashcards

Single disturbance travelling through medium

Particles move perpendicular to pulse direction

Max distance medium displaced from rest position

$A$

Width of disturbance

Amplitude & length stay constant

$v = \frac{D}{t}$

$m \cdot s^{-1}$

Medium properties, not amplitude or pulse length

Medium doesn't travel, only disturbance moves
