    Step-by-step explanation:

    We know that

    general equation of wave

    y(x,t)=Asin(kx−ωt)

    comparing this equation with given equation

    1) A=0.005m → amplitude

    k=80

    ω=3

    2) λ=

    k

    =

    80

    =(

    40

    π

    )m

    3) Time period T=

    ω

    =

    3

    sec

    frequency f=

    T

    1

    =

    3

    Hz

    4) Displacement at x=0.3m

    t=20 sec

    y=0.005sin(80×0.3−3×20)

    =0.005sin(24−60)=0.005sin(−36)

    =0.00495m

    y=4.9mm.
