Identify that waves transfer energy from one place to another without the net movement of particles. 2. Identify situations where waves transfer energy. 3. Define mechanical waves as waves requiring a medium for propagation. 4. Compare transverse and longitudinal waves and give examples of each. 5. Explain, using the particle model, the transmission of sound waves in different media. 6. Qualitatively describe wavelength, frequency, period, amplitude and speed of waves and show these aspects diagrammatically. 7. Investigate quantitatively the wave model including frequency, wavelength and speed using v=fλ. 8. Use speed = distance/time and apply this to the use of sonars in measuring distances to and from the seabed. 9. Identify that electromagnetic waves do not require a medium for propagation. 10. Relate the properties of different types of radiation in the electromagnetic spectrum to their uses in everyday life.
Understand the Problem
The question presents a series of tasks related to the study of waves, including definitions, comparisons, explanations, and applications. The user is expected to perform various analyses and investigations related to mechanical and electromagnetic waves, their properties, and their real-world applications.
Answer
Mechanical waves need a medium, electromagnetic waves don't. Waves transfer energy without net particle movement and include transverse and longitudinal types.
The concepts include understanding mechanical waves, electromagnetic waves, wave properties, and wave models. Mechanical waves need a medium for propagation, like sound waves. Electromagnetic waves do not need a medium. Transverse and longitudinal waves are types of mechanical waves, with transverse being perpendicular to the direction of energy transfer and longitudinal being parallel.
Answer for screen readers
