Q

Define oscillations

A

o An oscillation is any motion in which the displacement of a particle from a fixed point keeps changing direction and there is a periodicity in the motion i.e. the motion repeats in some way.

Q

Define phase difference

A

o phase (�) – the difference between the actual position of a sine wave at t=0 and zero. The value of � determines the displacement at t=0
