Here are the rest of the things 5. The next step is going to take some skill and some careful observation. The wave speed is associated with the movement of crests and troughs along the medium. Faster waves will have crests that move from the left side of the screen to the right side of the screen in less time; that is the crests move from left to right faster. Set the animation to a low frequency (about 0.1Hz) and observe the wave speed. It might help to put your finger or a pen cap on a crest and follow the movement from the left to the right along with the crest. Then repeat for a high frequency (about 1.0Hz). Make The observation of wave speed (the speed of the crest moving from left to right across the screen). Does this ten-fold increase in frequency - from about 0.1Hz to 1.0Hz - have any noticeable and appreciable effort upon the wave speed? Explain your answer and discuss your observations. 6. Does moving the Frequency slider from a low to a high value change the listed Wave Speed in this animation? Yes or No?7. Change the Wave Amplitude from a high value to a low value. In terms of particle motion, how would you describe the difference between a high amplitude wave and a low amplitude wave?8. Does a change in amplitude effect the wave speed? Run two tests with high and low amplitude using a similar procedure used in Question 5. Make a claim and support your answer with evidence.9. The wavelength of a wave refers to the length of the repeating pattern of crests and troughs. Long wavelength waves have crests that are spaced relatively far apart. Short wavelength waves have crests that are relatively close to each other. Use the controls to determine two ways to increase the wavelength of the waves. Describe what you did to increase the wavelength.

Directions: 0 Go to the following website: Wave Simulator 0 htt 5: www. h sicsclassroom.com Ph sics-lnteractives tortSimple-Wave-Simulatorlnteractive 0 Once you've launched the interactive and resized it, experiment with the interface. Tap on the slow motion, real time, and fast motion tabs at the top of the interface to observe how to control the tempo of the animation. Toggle back and forth between a sound wave and a rope wave by tapping on the \"show wave as\" button. Finally, observe the sliders at the bottom of the interface for controlling the frequency, wave speed, and wave amplitude. 0 Exploring waves on a rope: 0 Set the animation to show waves on a rope using a real time tempo and frequency, wave speed, and wave amplitude values of 0.10Hz (approximately), 100cm/s, and 2cm respectively. Then use the controls on the animation to answer the following questions. Procedure/Questions: Read the procedure and answer each question. Each question is worth 3 points each. 1. ln physics, we distinguish between wave motion and particle motion. Wave motion refers to the movement of a wave-like pattern from one location on the medium to another. When you view a water wave moving along the surface of water, you are observing wave motion. There is a very obvious movement of a collection of crests and troughs along the water surface. In the simple wave simulator; there is a collection of crests and troughs moving through a rope; this is wave motion. But there are also three points on the rope that are colored red. When you observe the motion of these points, you are observing particle motion-the motion of particles of the rope. Describe the motion of the particles. If you observe closely, you will notice that the particles leave a trail behind them as they move. The longer the trail, the faster the particle is moving. During any up-and-down cycle of the particle, does it move with a constant speed or with a changing speed? If the speed is changing, at which point during its motion does it move with the greatest speed? The smallest speed? There are a variety of wave to categorize waves. One way is to categorize waves as being transverse waves, longitudinal waves, or surface waves. Waves in each of these categories differ from one another in terms of how the direction of the particle motion compares to the direction of the wave motion. The waves traveling through the rope are transverse waves. For transverse waves, compare the direction that the particles move to the direction that the wave moves? Now use the frequency slider to increase the frequency to a high value. Compare the motion of the particles when the frequency is high to the low-frequency motion. How would you describe the difference
