THE FIRST TWO IMAGES IS WHAT I NEED HELP WITH (5,6,7,8) I've done the rest of the lab. If you want to see what the lab was, it is all under the first two images.

Wave Simulation Activity: Finding Wave Properties Objectives: Calculate and measure different wave characteristics (frequency, period, amplitude, wavelength). Describe the relationships among each of these wave characteristics Pre-Lab 1. Open simulation HERE or search Waves on a String PhET 2. Play with simulation. What things do you think change the wave shape?2. Play with simulation. What things do you think change the wave shape? The speed you move it and the height of it. 3. In what ways is this similar to the wave demonstration with the slinky? There are only the endpoints that are moving. In the slinky lab, we only had one person moving the endpoint. 4. You go to the beach on both days of the weekend. On Saturday, the weather is stormy and the waves are hitting the shore very frequently. On Sunday, the weather is calmer. Insert a screenshot of a wave that would be Insert a screenshot of a wave that would be described as: the Saturday waves with high described as: the Sunday waves with low frequency, high amplitude frequency, high amplitude OimailLab 1. Now hit the "reset" button. Make the following changes: a. Change the option from Manual to Oscillate. b. Change the end from "fixed end" to "no end". c. Set the damping to zero. 2. How does the amplitude affect the shape of the wave? The amplitude affects how far the antinode of the wave goes or how big the wave is. 3. How does the frequency affect the shape of the wave? The frequency affects the distance between each wave. Waves with a higher frequency have shorter wavelengths. Amplitude affects how high the wave goes. 4. Check your answers on the next two questions before going on. a. Using the timer, how would you measure the frequency of the wave in the simulation? (Assume you don't know the number that you set it at) You would measure the frequency of the wave by counting the number of waves that have passed a position in one second.b. How would you measure the period of the wave in this simulation? The period of the wave is the time it takes for one complete wave to pass a point. The period can be measured using the timer tool and measuring the time it takes for a complete wave cycle to pass a specific point.5. Keep the current settings: a. No end b. Hit reset c. Change damping to zero Choose one of the following tension settings (HIGHLIGHT the chosen one): High Medium Low Now find these quantities by filling in the table. Show your work if it requires a calculation. If you measured it, say that you measured it. There is a ruler and timer on the actual simulation if you choose to use it. Wave property Show work here (or say Final answer "measured"): (with correct units!) Frequency Period Wavelength Amplitude6. Keeping the wave on these settings. notice what happens to the green dots. As the wave travels forward {from left to right across your screen]. what happens to the green dots? How do they move?I [Focusing on just one dot at a time may help you gure this out.) o 1 If this were a wave at the beach; how fast do 1you think the crests of the wave would be moving towards you? Calculate the speed of the crests using your method. % 8. Play with the damping, frequency and amplitude. What additional observations do 1you make? List at least three. {Remember to change only 1 variable at a time, and control the rest of your va riablesl}
