This is a Physics question on the unit Sound

PBL: How can waves be used to perform a task? A wave is defined as a disturbance that travels through a medium from one point to another. (Class) What types of waves can you think of? (Class) What technologies use waves to perform a task? Identify a technology that your group will investigate (no EM waves): Job Prospects Name a career that involves the technology that your group investigated Career: Salary: Resource Acquisition Writ! of Resource _ Find a text resource that describes how the technology uses waves to function. Find a video resource that clearly shows how the wave travels to perform a task. Learning Goals Notes Use labelled diagrams to illustrate the learning goal concepts, include descriptions of key theory points Vibrations a. Describe longitudinal, transverse and torsional waves Draw labelled diagrams of longitudinal and transverse waves Define cycle, frequency, period, amplitude Differentiate between in-phase and out-of-phase Differentiate between a pulse and a periodic wave gunpo- Pictorial Representation of PBL & LG Label all parts, point form labels to indicate key parts and processes - Create a series of diagrams that describes how your technology works to perform your task. Use diagrams to help your description Application of Theory Use a labelled diagram if possible, Add point form labels to indicate key parts and processes - Equity: Identify one equity issue that this technology presents to society. PBL: How do noise cancelling headphones work? How do you maintain your razor sharp focus when studying if you have parents, siblings, neighbours, pets making noise to distract you? Physics found a way Noise Cancelling Headphones. Job Prospects Name a career that involves the physics of noise. Career: Salary: Resource Acquisition Type of Resource _ Find a text resources that explains how noise cancelling headphones work. Video Find a video resource that provides a clear visual representation of how noise cancelling headphones work. Learning Goals Notes Use labelled diagrams to illustrate the learning goal concepts, include descriptions of key theory points Interference of Waves a. Use the principle of superposition to describe how waves interact b. Explain the difference between constructive and destructive interference Pictorial Representation of PBL 8: LG Label all parts, point form labels to indicate key parts and processes - Use a series of labelled diagrams to explain how noise cancelling headphones function. 0 Labels should explain how the learning goals relate to the diagrams. Application of Theory Use a labelled diagram if possible, Add point form labels to indicate key parts and processes - Equity: How could the principle of superposition be used to solve an equity issue present in society? This could involve constructive or destructive interference
