Before answering the questions, practice moving the string on the Wave-on-a-String simulator using y our mouse (manual), in automatic (oscillate), or by pulsing (one wave at a time). Click oscillate and change the frequency and amplitude. Once you are comfortable with the simulator and video, answer the questions below, save the document, and then upload it to the correct dropbox in MyCourses. 1. Describe the differences between longitudinal and transverse waves. 2. Define frequency and amplitude. 3. Use arrows, or draw on the wave, show what will happen when the amplitude is increased. 4. Use arrows, or draw on the wave, to show what will happen when the frequency is increased. 5. Describe what happens to audible sound when frequency is changed. 6. Describe what happens to audible sound when amplitude is changed
