Properties Of Waves
Bayani Gaba-gaba
Every sound you hear, every colour you see and every mobile signal your phone picks up travels as a wave. Waves are one of the most universal ideas in physics, connecting topics from music and medicine to earthquakes and astronomy. Understanding their basic properties unlocks a huge part of the Edexcel specification.
In this topic you will learn how to classify waves as transverse or longitudinal, define the quantities that describe any wave, and use the wave equation to link speed, frequency and wavelength. You will also meet the Doppler effect and see how all waves can be reflected and refracted when they meet a boundary.
Manufura
- 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 between the speed, frequency and wavelength of a wave: wave speed = frequency x wavelength, v = f x lambda
- Use the relationship between frequency and time period: frequency = 1 / time period, f = 1 / T
- Use the above relationships in different contexts, including sound waves and electromagnetic waves
- Explain why there is a change in the observed frequency and wavelength of a wave when its source is moving relative to an observer and that this is known as the Doppler effect
- Explain that all waves can be reflected and refracted
