Now create a wave by moving your end of the spring toy towards and away from your partner. Th is called a longitudinal wave (also known as a compression wave). a) Sketch your wave below and draw an arrow to indicate which direction energy is being transported. b) Do the coils of the spring toy move in the same direction or perpendicular to energy transport? c) Can you think of a real-world example of a longitudinal wave? List at least one below. Part 3: Wave Amplitude 4 . Create a transverse wave with your partner. What happens to the waves when you increase or decrease the distance you move your hand back and forth? 5. The amplitude of a wave is the maximum distance moved by one point on the wave from its equilibrium position. Using your meter stick, measure the amplitude of your wave and record it below. Remember: you are measuring from the equilibrium point (the resting position) to the maximum displacement (not from one side to another). 6. Draw a diagram below showing what you measured and its length. Include units in your diagram. Part 4 : Wave Frequency 7. Create a transverse wave with your partner. What happens when you increase the rate you move your hand back and forth? 8. The frequency of the wave is how many wave pulses pass a point in a certain amount of time. Create a wave and measure the frequency by using a timer and fixed point. I recommend setting the timer for 10 seconds. Show your work below. number of cycles frequency = seconds
