Define amplitude, frequency, period, wavelength, and velocity of a wave; Relate wave frequency, period, wavelength, and velocity; Solve problems involving wave properties
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!
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.
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.
The energy and power of a wave are proportional to the square of the amplitude of the wave and the square of the angular frequency of the wave. Intensity is defined as the power divided by the area. …
In National 4 Physics examine the properties of waves and use the wave equation, v = f λ, to relate the speed, frequency and wavelength.
4 Δεκ 2023 · Explain that waves transfer energy, not matter. Distinguish between mechanical and electromagnetic waves. Summarize the major properties and behavior of waves, including (but not limited to) wavelength, frequency, amplitude, speed, refraction, reflection and diffraction. Educational Standards.
