question 25

Multiple Choice

Four traveling waves are described by the following equations,where all quantities are measured in SI units and y represents the displacement. I: y = 0.12 cos(3x + 2t)

III: y = 0.23 cos(3x + 6t)
IV: y = -0.29 sin(1.5x - t)
Which of these waves have the same speed?

• A) I and III
• B) I and IV
• C) II and III
• D) I and II
• E) III and IV
