The equation of a travelling wave is given by y=10cos[πt3+α]. If the displacement is 10cm at t=0, then the total phase at t=1.5s will be

The correct option is B (2π)rady=10cos(πt3+α)Substituting y = 10 and t = 0, we get 5=10cos(0+α)∴α=2πThe correct answer is (b)

The equation of a travelling wave is given by $y = 10 cos [\frac{π t}{3} + α]$ . If the displacement is $10 c m$ at $t = 0$ , then the total phase at $t = 1.5 s$ will be

The correct option is B $(2 π) r a d$
$y = 10 cos (\frac{π t}{3} + α)$ Substituting y = 10 and t = 0, we get
$5 = 10 cos (0 + α)$
$∴ α = 2 π$
The correct answer is (b)
