Question

A particle executes SHM along x and y axes with frequencies in ratio 1:2 and same initial phase. The Lissajous figure traced is:
  1. A
    Circle
  2. B
    Straight line
  3. C
    Figure-eight (∞ shape)
    Correct
  4. D
    Ellipse

Correct answer

Figure-eight (∞ shape)

Explanation

For f_x:f_y = 1:2 with zero phase difference, the Lissajous figure is a figure-eight. The specific shape depends on the phase difference and frequency ratio.
