Period and Frequency of Waves
The video explains two important features of a wave: the frequency and the time period. It uses a visual representation of a transverse wave and a longitudinal wave to show the peaks, troughs, amplitude, and wavelength of a wave. The...

How to Determine the Speed of a Wave on a String: Physics Experiment
This video explains how to conduct an experiment to determine the speed of a wave on a string. It shows the steps involved, such as setting up the string or wire, creating a wave on it, and adjusting the distance between the two ends to...

What is the Fourier Transform?
In this video, well look at the fourier transform from a slightly different perspective than normal, and see how it can be used to estimate functions.

Determining the Speed of a Standing Wave - Demonstration
The relationship between wavelength and frequency is determined. The number of waves, wavelength, and wave speed at each standing wave frequency is determined. The wave speed is measured independent from the standing waves.

How Is This Standing Wave Possible?
When standing waves are allowed at 15, 30, and 45 hertz on a string, then we should not see a standing wave pattern at 22 hertz. Yet, we do in this demonstration. This explains why.

Transverse and Longitudinal Waves _ GCSE Physics
Waves are vibrations that transfer energy from place to place without matter being transferred. Think of a Mexican wave in a football crowd: the wave moves around the stadium, while each spectator stays in their seat only moving up then...

How does laser cooling work?
Lasers are known to burn things, fix eyes, and dance on powerpoint presentations. But they can also be used to cool objects to some of the coldest temperatures in the universe.

Wave Mechanics
Surf's up, dudes! Somehow ocean waves got the illustrious honor of being simply called "waves", but there are tons of other kinds of waves, like light and sound. How do they work? We gotta know this stuff! Let's learn about waves together.

Wave-Particle Duality and the Photoelectric Effect
Look, up in the sky, it's a particle! It's a wave! Actually it's both. It's light! How do we know about this stuff? Well, because of Einstein for one. He did more than E = mc^2, you know. But don't stare at the sun to see for yourself,...

Standing Waves and Harmonics
Not all waves travel across the ocean or across the universe. Some are stuck in a certain spot! Like the vibrations of the strings on a guitar. What's the deal with these standing waves? And what's this, quantization? Oh my! We'd better...

Interference, Reflection, and Diffraction
Light and sound waves do all kinds of cool stuff, because they can be in the same place at the same time, unlike matter. This creates patterns that are important to understand! Let's take a look.
