How does ultrasound work? | Jacques S. Abramowicz
In a dark cave, bats can't see much. But even with their eyes shut, they can navigate rocky topography at incredible speeds. This is because bats aren't just guided by their eyes, but rather, by their ears. It may seem impossible to see...

Wavelength
In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

Wave Speed
In this video Paul Andersen explains how the wave speed measure the speed of a wave through a medium. The medium determines the speed of the wave. The velocity of the wave is equal to the product of the wavelength and the frequency of...

Doppler Effect
In this video Paul Andersen explains how the perceived frequency of a source depends on the motion of both the source and the observer. As a source approaches an observer the frequency will increase and as it moves away it will decrease....

Wave Period and Frequency
In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are...

Wave Equation
In this video Paul Andersen explains how a sine or cosine wave can describe the position of the wave based on wavelength or wave period. A wave function can the position of a wave as a function or the amplitude and wavelength or the...

Movimiento Ondulatorio - Física
Todas las ondas pueden transferir energía de un lugar a otro sin transferir materia. Esto se logra mediante una serie de perturbaciones o vibraciones que transportan la energía. Al igual que las personas en sus asientos, que solo se...

Wave Motion
Wave Motion | Waves | Physics | FuseSchool All waves can transfer energy from one place to another without transferring any matter. This is done by a series of disturbances or vibrations that carry the energy. Just like the people in...

Bozeman Science: Beats
In the following video Paul Andersen explains how beats are created through interference of waves with similar frequencies. The changes in amplitude are caused by destructive and constructive interference. The frequency of beats is equal...
