A progressive wave transfers energy without transferring material and is made up of particles of a medium (or field) oscillating e.g. water waves are made of water particles moving up and down.
Phys 211 Formula Sheet. Impulse. I = F dt. P = Fav t. Collisions: If FEXT = 0 in some direction, then. Pbefore = Pafter in this direction: mivi (before) = mivi (after) In addition, if the collision is elastic: Ebefore = Eafter.
12 Ιαν 2023 · Figure 8.6.2: Beats. The blue envelope wave on the combined plot outlines the change in amplitude. One can see when the envelope function is at peak, the two individual wave overlap at the same displacement (crests in this figure) resulting in constructive interference at that location.
The wave equation links the speed, frequency and wavelength of a wave. This is relevant for both transverse and longitudinal waves. The Wave Equation. The wave equation tells us that for a wave of constant speed: As the wavelength increases, the frequency decreases.
Intensity of a wave vs. amplitude. Intensity of a wave’s radiation at a certain distance from the source. Transmitted intensity of light incident on a polariser (Malus’s law).
An accurate technique for determining how and where waves propagate is given by Huygens’s principle: Every point on a wavefront is a source of wavelets that spread out in the forward direction at the same speed as the wave itself. The new wavefront is a line tangent to all of the wavelets.
