Question
Two wave are represented by equation y1 = a sin ωt and y2 = a cos ωt the first wave : -
Options
A.leads the second by
B.lags the second by π
C.leads the second by 
D.lags the second by
Solution
y1 = a sin ωt
y2 = a cos ωt = a sin (ωt + π/2)
y1 lags y2 behind by phase
y2 = a cos ωt = a sin (ωt + π/2)
y1 lags y2 behind by phase
