Question:

Four waves are described by the following equations, in which all distances are measured in centimeters and all times are measured in seconds:

yA = 10 cos(3x - 4t)

yB = 10 cos(5x + 4t)

yC = 20 cos(-10x + 60t)

yD = 20 cos(-4x - 20t)

(a) Which of these waves travel in the +x direction?

(b) Which of these waves travel in the -x direction?

(d) Which wave has the greatest wavelength?

(e) Which wave has the greatest speed?
