Unformatted text preview: , which is the same for cases 1- 3. For which of the following displacement func5ons for sinusoidal waves is the speed of wave propaga5on the largest? Explana/on: The correct answer is 5. For sinusoidal waves, D = D_o sin(kx ± ω t + φ), the speed of the wave is ω/k. For which of the following displacement func/ons for sinusoidal waves propaga/ng on a rope is the maximum speed of the rope the largest? Explana/on: The correct answer is 4. The velocity of the rope is simply the /me deriva/ve of the displacement. Two wave pulses, shown below, are propaga5ng toward one another on a string: Which of the following DOES NOT represent a possible superposi5on of the two waves as they pass through one another? Explana/on: The correct answer is 2. As the waves pass through each other, they will never completely destruc/vely interfere. Two ropes, one thick (heavy) and one thin (light) are aFached together to form one long string; this composite string is kept under tension T. A wave propagates down this string star5ng on the thick sec5on and traveling into the thin sec5on. AJer the wave passes the knot, which of the following changes? (1)frequency only (2)wavelength only (3)wave speed only (4)frequency and wave speed (5)wavelength and wave speed (6)frequency and wavelength Explana/on: The correct...
