Two Waves Are Traveling on Two Different Strings $\omega$

question 29

Multiple Choice

Two waves are traveling on two different strings.The displacement of one is given by y₁(x,t) = y_msin(kx + $\omega$ t) and of the other by y₂(x,t) = y_msin(kx + $\omega$ t + φ) .What is the difference between these two waves?

• A)The displacement of wave y₁ is always greater than the displacement of wave y₂.
• B)Wave y₁ has a smaller amplitude than wave y₂.
• C)Wave y₁ has a higher frequency than wave y₂.
• D)Wave y₁ has a shorter wavelength than wave y₂.
• E)The two waves are identical except for their displacement at time t = 0.
