Objective: Explore transverse and longitudinal waves as well as examples of each. Part 1: exploring amplitude and pulse waves Background video: https://www.youtube.com/watch?v=RVyHkV3wlyk Vocab definition image Amplitude: energy a wave has. High-Energy Wave Low-Energy Wave AAA The amplitude of a wave is related to the energy which it transports. Frequency: number of waves that pass Time by per second Low Frequency Medium Amplitude Frequency High Frequency Periods: Length of time for a save Time Period to complete. amplitude Wavelength: distance between two crests. Wavelength Crest Crest Trough Crest/Trough: Crest=the highest point on a wavelengthTrough the lowest point Crests on a wavelength Troughs Instructions for measuring frequency, periods, and wavelength in a simulation: (click the link to open the simulation) https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html Use the demonstrations below to help you measure the "period" and "wavelength" Demonstration: Measuring the period. https://www.youtube.com/watch?v=QRzSha78gPc Demonstration: Measuring the Wavelength: https://www.youtube.com/watch?v=P-3PEbpIsww 1. Select oscillate, slow motion, timer, and rulers. Make sure your O Manual Restart boxes look like Fixed End . Oscillate Loose End Pulse this. No End -T 10 cm Timer Oscillator 00:00.00 Slow Motion Normal 5 D Amplitude Frequency Tension 0.75 cm 1.50 Hz Damping _Rulers None Lots Low High Timer Reference Line 2. Set the amplitude to 1 cm (This will stay the same). 3. Set frequency to .5Hz.Amplitude Frequency 1.00 cm D 0.50 Hz 4. Pause ( )the simulation when the oscillator is at the bottom of it's cycle. D 00:00.00 D 5. Click play ( jon your timer It should not start yet. 6. Click play ( ) to start the simulation. The waves and the timer will start. 7. Click pause ( ) when the oscillator is back at the bottom of the cycle . This means 10 cm oscillator is at the bottom of the cycle you have made one wave. Ocm 2 3 8. Use the ruler ( I) to measure wavelengths. 9. Record your data in the table below (a period is how long it takes to make one wave). ***Repeat steps 1 - 9 for 1Hz, 2Hz, and 3 Hz (change the frequency ONLY/do NOT change the amplitude).*** Frequency Period (Unit=S) Wavelength (Unit=Cm) 1 Hz 2 Hz 3 Hz 1. Based on observations, What is wavelength? 2. Based on observations, What is a period?Based on observations, what is frequency? Based on observations, What is the relationship between frequency in period. (compare and contrast}. Give an example to defend your answer. Based on observations, what is a question you still have about waves
