oScienceScene.com Sound Waves Learning Objectives: PHSA 1050 Topic 8 In Class January 2023 Explore and draw conclusions about the nature. properties and behaviors of sound waves. Use the simulation to develop your own definition of frequency and amplitude. Describe how frequency and amplitude affect the sounds we hear. Given a description of a sound like "high pitched and loud". describe the amplitude and frequency. Calculate the speed of sound. and sound waves. 10. Discuss examples of things that make the different types of sounds listed in the table below. Write your examples in the table below. Play the Sound Waves simulation https://phet.colorado.edu/en/simulations/sound. Use the Listen to a Single Source tab. Turn on the Audio Enabled so you can hear the sound. Adjust the Frequency and Amplitude using the control panel provided. Create the sounds in the table below. 01 192015 bra Terfull grab bin moleare s ne Mould .
