P1.5.2 Measuring Waves 0.0 / 5 ? PhysicsWavesGCSEAQA Created by: MaddiCreated on: 30-04-14 13:07 What do we mean by the amplitude of a wave? The amplitude of a wave is the height of the wave crest or the depth of the wave trough from the position at rest. 1 of 5 What do we mean by the frequency of a wave? The frequency of a wave is the number of waves crests passing one point in one second. 2 of 5 What do we mean by the wavelength of a wave? The wavelength of a wave is the distance from one wave crest to the next wave crest. 3 of 5 What is the relationship between the speed, wavelength and the frequency of a wave? speed = frequency x wavelength 4 of 5 What is the units for speed, frequency and wavelength? Speed: m/s. Frequency: Hz. Wavelength: m. 5 of 5
