CLASSWORK & ASSIGNMENTS
WAVE AND SOUND ANIMATIONS
Transverse Wave
by Dan Russell Pennsylvania State University A transverse wave is a sinusoidal wave. The matter is disturbed perpendicular to the direction that the wave energy moves. Again, the wave carries the energy, but not the matter. The matter is disturbed up-and-down, but is not carried away by the wave. |
Standing Wave Formation
by Dan Russell Pennsylvania State University Forming a standing wave. A standing wave forms when two series of waves moving in opposite direction exactly overlap. The two wave functions must have the same frequency and wavelength. The reflecting waves (from the pole, moving right to left) overlap with the incoming waves (from the source, left to right) to form the standing wave. The waves are actually moving from left-to-right then right-to-left, however the result is that waves seem to only move up and down. |
Standing Wave: Wave Superposition
by Dan Russell Pennsylvania State University Forming a standing wave. A standing wave forms when two series of waves moving in opposite directions exactly overlap. The two wave functions must have the same frequency and wavelength. Two different wave functions with the same frequency and wavelength, but moving in opposite directions, are overlapping (blue top, red middle) The heavy black wave (bottom) is the resultant wave, the sum of the two wave functions. The resultant wave is a standing wave. Though not readily visible, the blue wave still moves left-to-right and the red-wave still moves right to left. |
Frequency and Wavelength
By Stick Man Physics Wave Math High frequency wave vs. Low frequency wave. The upper wave is the high frequency wave. Many waves are produced in a short amount of time. The lower wave is a low frequency wave. Fewer waves are produced. Frequency and wavelength are inversely proportional to each other. Higher frequency will make shorter wavelengths--more waves but shorter. Lower frequency will make longer wavelengths--fewer waves but longer. |
Constructive Interference by Wave Pulses
by Dan Russell Pennsylvania State University Two wave pulses superimpose. Both wave pulses are in the same phase, or in-phase to each other (both oriented up). When they cross, the resultant wave has a larger amplitude than the two component waves. This is constructive interference. After the two waves superimpose and pass through each other, they continue as they were before--same frequency, wavelength, amplitude, and wave speed. |
Destructive Interference by Wave Pulses
by Physics Stack Exchange Two wave pulses superimpose. The wave pulses are in the opposite phase, or out-of-phase to each other (one oriented up, the other oriented down). When they cross, the resultant wave has a smaller amplitude than the two component waves. This is destructive interference. In this case, the two waves being identical in wavelength and amplitude, but out-of-phase, create a zero amplitude resultant wave (total destructive interference) as they cross. After the two waves superimpose and pass through each other, they continue as they were before--same frequency, wavelength, amplitude, and wave speed. |
Beats
by Dan Russell Pennsylvania State University Beats are short intervals of greater amplitude and wave signal. Beats are formed by the overlap of two wave systems that are slightly out of frequency with each other. As the two wave systems overlap, some places are overlapping in-phase and producing constructive interference (the beat, stronger signal). Other places are overlapping out-of-phase and producing destructive interference (the node, weaker signal). |
Tuning Fork and Sound Waves
by Flipping Physics Sound waves are longitudinal waves that are created by a vibrating object, like a string in a musical instrument on by the tines on a turning fork. The vibrating tuning fork tines push on the particles of the medium, creating a traveling wave pulse. The wavefront of the sound wave is the compression part of the wave. The sound wave moves through the medium. The medium is disturbed by the traveling sound wave, but the particles of the medium are not carried with the waves. |
