PHYS- | Waves Gizmo | Knowledge Q&A | 100% Correct

Deselect the Lights on checkbox. What is the motion of the green dot? The green dot is going in a circle. In a combined wave, the motion of the medium is circular. So, each point of the spring moves in a circle as the wave is transmitted from left to right. C. Click Pause. Compare the crests (high points) to the troughs (low points). What do you notice? The crests are more spaced out and the troughs are closer together. Combined waves, such as ocean waves, do not look exactly like transverse waves. In the Gizmo, the troughs are pointy and the crests are rounded. In the ocean, the crests are relatively pointy while the troughs are rounded. 2. Measure: Click Reset. Select Lights on and Show rulers. Set the Frequency to 1.0 Hz. Check that the Tension is 2.0 N, the Density is 1.0 kg/m, and the Amplitude is 10.0 cm. A. Measure the horizontal distance between two crests. What is this distance? 145cm B. What is the distance between two troughs? 142cm C. How do the wavelength, wave speed, and wave power of the combined wave compare to a transverse wave with the same settings? Explain. D. Why do you think the combined wave is more powerful than either the transverse or longitudinal wave with the same amplitude, frequency, tension, and density
