Please answer the questions at the end (1-5)
A: B: C: D: 13. Remove the slinky from the book/wall so that end of the slinky is again "free". Tie the end of a thin string to one end of the slinky. While your partner is holding the free end of the string firmly (about 0.5m or 2 feet of string should be between the hand and the slinky) and you are holding the free end of the slinky, you send a large transverse pulse through the slinky towards the string. Carefully observe the reflected pulse in the slinky (it may be small) as it reflects from the string. The string represents a less-dense medium (as compared to the slinky). Does a wave reflected from a less-rigid medium return upright or inverted as compared to the original pulse? The was in upright 14. Regarding your experiment in #12 above, will the reflected wave contain as much energy as the original wave? Why? 1 luxes energing becerase it lust momentum 15. In the diagrams below, two computer-generated pulses are traveling toward each other. Draw the result when they meet (and occupy the same space for a moment). r Questions 1.
