please help with these old physics questions?
The wave number and the angular frequency are 6.2rad/m and 12 rad/s. what could be the equations of the wave?
all of the above
Find the displacement of the wave y= 12sin(6.28x-3.14t) when x=2m and t=4s

1) the equation for a travelling wave is given by
y= a sin (kx-wt)
k= wave number= 6.2 rad/m
w=angular frequnecy= 12 rad/s
so y= 8 sin(6.2x-12t)
2) y = 12*sin((6.28*2) - (3.14*4))
y = 12*sin0
y = 0
