PHY 2049 Virtual Lab Oscillations and Waves Name Perform the following steps: 1. Go to the University of Colorado Physics simulation webpage (the link is provided in Canvas) 2. Scroll down to the simulation \"Mass spring basics\" and click on that simulation. 3. Click on \"bounce.\" 4. With your cursor, move 100g block to each of the two springs and watch them bounce. 5. With your cursor, check the boxes for \"unstretched length" and \"resting position.\" 6. Using the slider for spring 1, increase the strength of spring 1 to its maximum. How does that change the resting position and period of spring 1'? 7. Stop the simulation and return to the menu of simulations. 8. Continue scrolling down to the simulation \"Waves on a string\" and click on that. 9. Click the arrow. 10. Manually with your cursor, move the appliers up and down and observe what happens. 11. Near the top left, click on \"pulse\" the click on the green button on that appears below and observe what happens. 12. Click on oscillate and observe what happens. 13. What is the difference in motion between the \"pulse\" and \"oscillate?\" 14. Near the top right of the screen, click on \"loose end\" and repeat steps 1012. 15. Go to the website NDT Resource Center section on ultrasound and Ultrasonic Testing (the link is provided in Canvas). 16. What does the acronym NDT mean? 17. Scroll down and watch the animation that automatically runs. Describe what it shows
