Two Traveling Sinusoidal Waves Interfere to Produce a Wave with the Mathematical

question 23

Multiple Choice

Two traveling sinusoidal waves interfere to produce a wave with the mathematical form If the value of $\phi$ is appropriately chosen, the two waves might be:

• A) y₁(x,t) = (y_m/3) sin (kx + \( \omega \)t) and y₂(x,t) = (y_m/3) sin (kx + \( \omega \)t + \(\phi\))
• B) y₁(x,t) = 0.7y_m sin (kx - \( \omega \)t) and y₂(x,t) = 0.7y_m sin (kx - \( \omega \)t + \(\phi\))
• C) y₁(x,t) = 0.7y_m sin (kx - \( \omega \)t) and y₂(x,t) = 0.7y_m sin (kx + \( \omega \)t + \(\phi\))
• D) y₁(x,t) = 0.7y_m sin [(kx/2) - (\( \omega \)t/2)] and y₂(x,t) = 0.7y_m sin [(kx/2) - (\( \omega \)t/2) + \(\phi\)]
• E) y₁(x,t) = 0.7y_m sin (kx + \( \omega \)t) and y₂(x,t) = 0.7y_m sin (kx + \( \omega \)t + \(\phi\))
