Lissajous figures
This simulation shows the superposition of two perpendicular harmonic
oscillations. We have
x = A1 cos(ω1
t)
in the horizontal direction and
y = A2
cos(ω2 t + φ)
in the vertical.
Above
one can see the evolution of the phasor for the horizontal oscillation and
on the left the one for the vertical motion.
-
You can choose in the left panel the amplitudes A1 = A1
and A2 = A2, the frequencies ω1 = ω1
and ω2 = ω2 and the relative phase φ
(in degrees), as well as the interval Δt between points
and their number.
