Given :
y = 0.02 cos (πx) sin (100 πt)
y = R sin 2πnt
where R= 2A Cosπ 2 x/λ
y = 0.02 cos (πx) sin (100 πt)
y = 0.02 cos 2(πx/2) sin [2π(50)t)
By comparing the given equation with
Y=R sin2π nt
Where
R=2A Cos 2πx/λ
Where A= amplitude =0.01m
A=wavelength=2m
N= frequency =50Hz
T=time period=1/n=1/50=0.025
V= velocity =nλ=50x2
V=100m/s
