This video provides an introduction to the speed of sound in air and demonstrates several methods to measure or calculate it. It also presents equations to calculate the speed of sound based on the wavelength and frequency of a sound...

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...

This is a lecture video that explains various methods used to measure the speed of waves. The video starts by introducing two equations that can be used to calculate the wave speed. It then focuses on two examples to explain how to use...

This video is a lecture on how waves change as they cross the boundary between different materials, also known as changes of medium. The video explains what a medium is and how it affects wave propagation. The video uses examples of...

This video discusses the properties that all waves have in common, including amplitude and wavelength. It also demonstrates how to calculate the speed of a wave using the equation v = Fλ, where v is the wave speed, F is the frequency in...

Live-action video footage of everyday examples illustrate the relationship between speed and energy. The program helps students setup an activity in which they gather data to calculate the speed of moving objects. In turn, students will...

This video is a lecture on echo sounding, a technique used by ships to locate objects beneath the surface of water. The video explains how ultrasound is partially reflected at the boundary between two different media, which is used to...

The video is a lecture presentation on the concepts of speed, displacement, and velocity. The presenter explains the meanings of these terms and the relationships between them. The examples used in the presentation help to illustrate the...

This video is a lecture that explains the relationships between wave speed, wavelength, and frequency of a wave. It starts by defining a transverse wave and discussing the amplitude, wavelength, frequency, and time period of a wave. The...

The range of human hearing is 20Hz to 20,000Hz. Ultrasound waves are just sound waves with a frequency above 20,000Hz. When ultrasound reaches a boundary between two media with different densities, some are partially reflected back and...
