Properties Of Waves
Gbogbo ọrọ náà
Drop a stone into a still pond and something travels outwards across the surface, yet the water itself stays where it was. That is the strange and powerful idea at the heart of this topic: a wave moves energy and information from place to place without carrying any material with it.
In this lesson you will learn the vocabulary that describes every wave, from a ripple in a tank to a radio signal from a satellite, master the wave equation that links speed, frequency and wavelength, and see why every wave, without exception, can be reflected and refracted.
Ebumnobi
- 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 between the speed, frequency and wavelength of a wave: v = f x lambda
- Use the above relationships in different contexts including sound waves and electromagnetic waves
- Explain that all waves can be reflected and refracted
