A wave is described by y = (2.05 cm) sin(kx - t), where k = 2.13 rad/m, = 3.58 rad/s, x is in meters, and t is in seconds, how do you determine the amplitude, wavelength, frequency, and speed of the wave?
I think there is something missing...
I may be wrong but I think there is a bit missing from your wave:
The amplitude is the number in front of
You get the wavelength
Frequency is found from
Finally, speed will be
