A wave causes a displacement y that is given in meters according to y=(0.45) sin (8.0 * 3.14t - 3.14x), where t and x are expressed in seconds and meters.
a.) What is the amplitude of the wave?
b.) what is the frequency of the wave?
c.) What is the wavelength of the wave?
d.) What is the speed of the wave?
e.) Is the wave traveling in the +x or -x direction?
The solution shows how to find out the following parameters of the wave: amplitude, frequency, wavelength, speed, and direction.
