The oscillations represented by curve 1 in the graph are expressed by equation x = A sin ωt. The equation for the oscillations represented by curve 2 is expressed as
A
x = 2Asin(ωt - π/2)
B
x = 2A sin(ωt + π/2)
C
x = -2Asin(ωt - π/2
D
x = A sin(ωt - π/2)
Answer
x = 2Asin(ωt - π/2)
Explanation
Solution
Oscillations represented by 2 lags in phase by n/2 and periods are same. Amplitude of wave 2 is double that of wave 1.
