The unknown to the known frequency for Lissajous patterns on a Cathode Ray Oscilloscope (CRO) is given by:
\(f_y=f_x({n_x\over n_y})\)
where, fy = Vertical frequency
fx = Horizontal frequency
nx = No. of horizontal tangencies
ny = No. of vertical tangencies
Calculation
Given, ny = 10 and nx = 8
fx = 1000 Hz
\(f_y=1000\times ({8\over 10})\)
fy = 800 Hz
