Instructional objectives
Students should be able to:
- Demonstrate understanding that waves transfer energy without transferring matter
- Describe what is meant by wave motion as illustrated by vibration in ropes and springs and by experiments using water waves
- Use the term wavefront
- Give the meaning of speed, frequency, wavelength and amplitude
- Distinguish between transverse and longitudinal waves and give suitable examples
- Recall and use the equation v = f λ
Teaching Process
- Discuss the mechanism of generation of a wave.
- Show how waves transfer energy without the transfer of matter.
- Discuss the importance of the terms wavelength, amplitude, frequency, time period
- Discuss the difference between mechanical and non-mechanical waves
- Discuss the difference between transverse and longitudinal waves
- Derive v = f λ
Activities
- demonstration of non-transfer of matter, by showing how a floating ball on water only moves up and down as a ripple passes it.
- Demonstrate transverse and longitudinal waves in a slinky
- Derive v = f λ by making them do a mexican wave
Assignments / Evaluation
- Numerical problems
- Written test
