Final answer:
Savannah should use a button or setting within her audio or video editing software to view audio waveforms, with common options including toggling 'Show Audio Waveform.' In an oscilloscope experiment, she can adjust amplitude and frequency to visualize and understand sound waves and their interaction with various elements.
Step-by-step explanation:
If Savannah needs to view audio waveforms in the Timeline, she should look for a button or a setting within her audio editing or video editing software that allows her to toggle the visibility of audio waveforms. Since the question doesn't specify the software being used, it's important to understand that most audio and video editing programs provide a feature to display audio waveforms to help users edit sound more accurately. In programs like Adobe Premiere Pro, there is usually an option to 'Show Audio Waveform' by right-clicking (or Ctrl-clicking on a Mac) within the Timeline panel. Similarly, other software such as Audacity has a waveform view that is typically visible by default.
When using an oscilloscope in a simulation or real-life scenario, you adjust the controls like amplitude and frequency to display the characteristics of the sound being produced. The microphone converts the sound to an electrical signal shown on the oscilloscope. Features such as frequency, amplitude, triggering, and channels are the main controls in an oscilloscope and are key to viewing and understanding sound waves and their behaviors in different situations, such as when there's interference or reflection.
To conduct an experiment and see sound waves, Savannah can adjust settings within a simulation to alter frequency or amplitude. She can add further complexity to the experiment by introducing a second speaker or barrier, experimenting with two-source interference, or exploring interference by reflection. This hands-on approach can provide visual and auditory feedback on how sound waves behave and interact with different variables.
