Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....

The conversion of sound into light is a fascinating phenomenon that is a side effect of pistol and mantis shrimp stunning their prey. It is known as sonoluminescence, and it is thoroughly delineated in this fascinating little video. Add...

How do you create the sound of hydrogen? An interesting video explains how to use mathematical formulas and sound software to translate the spectrum of light that comes from hydrogen into a sound. The resource walks through each...

Installment four of the nine-part series on using Audacity describes saving, exporting, and deleting podcasts you've made. If you read the excerpt under this video as it comes on you're screen you'll notice a web link. This takes you to...

Hydrogen is odorless, colorless, and tasteless, but can we hear it? By taking the wavelengths of the atomic spectrum of radiation from hydrogen, the creator of the video shifts the waves into sound waves. Then, he shifts these waves into...

Calculating frequency is so easy it Hertz! The video begins by describing transverse and longitudinal waves, and then it explores their properties and applications. Finally, it applies this to the formulaic relationships between wave...

Does your lesson plan for wave properties have its ups and downs? Get some fresh ideas from an informative video! The narrator discusses PS4A, showing the must-know ideas for each grade level through concept maps and demonstrations.

 Introduce classes to the idea of waves with a short video clip. An interesting presentation gives a quick but thorough overview of the different types of waves and where people encounter them.

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

Holding a conversation underwater has its challenges. Sound and light waves can travel in different mediums, but it affects their waves. The video explains the process of refraction and diffraction and how it relates to energy waves. 

The universe is getting bigger and bigger! A video features an instructor explaining the Big Bang Theory and gives evidence to show the universe is still expanding. Discussion includes the doppler effect and the red-shift in the light...

Explore the physics of tuning most musical instruments. The video instructor explains the pitches of string and wind instruments with an emphasis on the sound waves. After discussing the ratios between pitches, it compares harmonics and...

The mantis shrimp's claws snap to produce a bubble that is as hot as the sun. How they manage to do that is the focus of a video on the cavitation caused by the shrimp and how the creature is able to create sonoluminescence....

Would an evil mastermind trying to take over the universe use explosives in space? A video that is part of a larger series approaches this question with physics of course! She explains the role of the atmosphere, the properties of waves,...

Why do dissonant noise cause a physical reaction of fear in humans? The video explains why some things sound scary and how we evolved to be more afraid of sounds than sights. It details how people constantly live in the past and how...

Scientists have theorized about the merging of stars based on scientific theories and mathematical principles. For the first time, observation has confirmed these theories. Viewers share in the excitement of the discovery as they watch...

Aristotle said, "The more you know, the more you know you don't know." Physics includes everything from the laws of motion to quantum gravity. An interesting video attempts to cover the main concepts of every branch of physics in only a...

How do you get the most light out of a light bulb? That's the task Max Planck took on, and it turned out to be rather...enlightening! The illustrated video introduces physics scholars to Planck's plight, which ultimately changed our...

Legolas counts the number of riders on steeds at a distance of five leagues away, including knowing their colors and height, in J.R.R. Tolkien's Lord of the Rings. A video researches this possibility by starting with the...

One of the most flammable sports balls turns out to be ping pong balls. Watch a ping pong ball burn using Schlieren imaging. The video details how Schlieren imaging works in color, black and white, and in slow motion. 

Paul Andersen explains how waves interact with objects and other waves. When a wave hits a fixed object, it will be reflected and inverted. When a wave hits a free object, it will be reflected without being inverted. [6:24]

Discover sounds when Quack gives Chirp the silent treatment, and Chirp gets stranded in a puddle. [8:50]

David explains wave interference and solves a few examples to find the value of the total wave when two wave pulses overlap. [7:24]

David explains how and why standing waves occur, and well as how to determine the wavelengths for a standing wave on a string. [13:25]
