Consider a mechanical wave described by the wave function $y(x,t)=6sin(9x-3t)m,$ where $x$ is the position in meters along a string and $t$ is time in seconds.

The amplitude of the wave is meters.

The wave number is $$ adians$/$meter$.$

The angular frequency i $$ radians$/$second$.$

The wavelength is $$ meters

The frequency is $$ Hertz
