Wave Representations Model. A flexible model that displays motion of a wave on a string alongside Displacement/Time graph for two points on the string. Using only these representations, you can determine amplitude, period, wavelength, and wave speed. Run as a simulation or customize for your class. Worksheet included.
A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave. A wave’s frequency can be measured by how many crests (or how many troughs) pass a location in a certain amount of time.
This particular Concept Builder pertains to the five characteristics of waves - frequency, period, wavelength, amplitude, and speed. There are typically multiple levels of difficulty and an effort to track learner progress at each level.
The amplitude of a wave is a measure of the displacement of the wave from its rest position. The amplitude is shown on the graph below. Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position.
28 Δεκ 2020 · Shorter wavelengths are associated with higher frequencies and high energy, while higher frequencies sit on a short-wavelength portion of the spectrum with longer wavelengths.
Frequency tells us how many waves are passing a point per second, the inverse of time. Wavelength tells us the length of those waves in metres, almost like a displacement. If we multiply these two together, we are really multiplying 1/s and m … which gives us m/s, the velocity of the wave!
