Simple harmonic motion mains 2018:

Q. 28. Two simple harmonic motions, as show below, are at right angles. They are combined to form Lissajous figures. 


x(t)= A sing (at+8)
y(t)= B sing (bt)'
Identify the correct match below. 

Option :
1 .   A B ,   a = b ;   8 = π / 2   Ellipse 2 .   A = B ,   a = 2 b ;   8 = π / 2   CIrcle 3 .   A B ,   a = b ;   8 = 0   Parabola 4 .   A = B ,   a = b ;   8 = π / 2   Line
