please give the 4 answers it askes on the bottom of the page.
Date, Class, 1 of 2 tics of Waves Enrich Interference of Pulses Suppose that you are holding one end of a rope and a friend is holding the other end. If you give a flick to your end of the rope, a single wave will travel down the rope toward your friend. This single wave is called a pulse. Now suppose that you and your friend each give an upward flick to the rope at the same time. In this case, two pulses will travel down the rope, but in opposite directions. Figure 1 shows what happens as the pulses travel through each other. As you can see, the amplitudes of the pulses “add" together as the pulses meet. Figure 2 shows what would happen if you gave an upward flick to the rope at the same time as your friend gave a downward flick to the rope. In this case, one of the pulses moves the rope above its resting position, and the other pulse moves the rope below its resting position. When these two pulses travel through each other, their amplitudes also "combine." In this case, however, you can think of the amplitude of the downward pulse as being “subtracted" from the amplitude of the upward pulse.
