Properties Of Waves
Akopọ
Waves carry energy from one place to another without transferring matter. From sound crossing a room to light arriving from a star, the same principles apply.
In this lesson you will learn the difference between transverse and longitudinal waves, key wave properties (amplitude, frequency, wavelength, period), the wave equation v = f lambda, the Doppler effect, and how all waves can be reflected and refracted.
Awọn Afojusun
- Explain the difference between longitudinal and transverse waves
- Know the definitions of amplitude, wavefront, frequency, wavelength and period of a wave
- Know that waves transfer energy and information without transferring matter
- Know and use the relationship: wave speed = frequency x wavelength
- Use the relationship between frequency and time period
- Use wave relationships in different contexts, including sound waves and electromagnetic waves
- Explain the Doppler effect
- Explain that all waves can be reflected and refracted
