The equation of a wave disturbance is given as :
 where X and y are in metres and t in seconds. Choose the wrong statement:

Detailed Solution for Waves MCQ Level - Question 1

y=0.02cos(π/2+50π∗t)cos(10π∗x)

At x=0.3m
y=0.02cos(π/2+50π∗t)cos(3π) = −0.02cos(π/2+50π∗t) (It is right)

Now compare the given equation by the standard stationary wave equation,

y=Acos(ϕ+ω∗t)cos(2π/λ∗x)

2π/λ=10π, λ=0.2m (it is also right)

At x=0.15m, 

y=0.02cos(π/2+50π∗t)cos(π/2),

and

v=Aω=0.02∗50π=πms−1

so option d is incorrect.
