Mr. Andersen explains how sound waves are created and perceived. A brief discussion of pitch and loudness are included. A generated sound of varying pitches is also included.

Invisible to the naked eye, our night sky is scattered with the 100s of billions of galaxies the fill the known universe. Like the stars, these galaxies form constellations – hidden patterns that echo the reverberations of matter and...

Sound Waves In Action | Waves | Physics | FuseSchool Did you know that birdsong is a disturbance? In this video we will look at how sound waves travel and see them in action: how a Ruben’s tube shows sound waves and how the human ear...

Sound Wave Experiments In this video, we are going to look at the factors that influence the speed of sound and how to measure it. We will look at sound waves in more detail in another video: Sound Waves Sound travels at about 340m/s in...

This video covers: - How sound waves travel through materials - The idea that sound waves are longitudinal - How wavelength changes with speed - The structure of the human ear and how it works - How the range of human hearing changes...

Discover the characteristics of sound waves, including wavelength, frequency, and pitch. Learn about the Doppler effect and its impact on sound perception. Explore how acoustics influence building design and sound control. Sound part 3

In this video Paul Andersen explains how the energy of a wave if directly related to the amplitude of a wave. The wave energy of a sound wave is the volume of the wave.

This video explains how sound waves can be displayed on an oscilloscope and how the amplitude and frequency of the waveform relate to the loudness and pitch of the sound. The video uses examples of different sound waves and the...

This video explains how sound waves travel through the air, solids, and liquids to reach our ears. It explores how vibrations create sound waves, which are collected by our ears and make our eardrums vibrate. Our brain recognizes these...

The video “Catching a Sound Wave'' gives a general overview of how sound waves travel, with a focus on the phenomenon of echoes and how they are used in nature and science.

When you hear the roar of traffic, the bark of a dog, or your teacher's voice, you are experiencing sound. This program uses colorful animations to explore important characteristics of sound, including intensity, loudness, pitch, and...

How many decibels would be recorded by the loudest sound waves your ears could possibly process? The loudest sound might be quieter than you think (because of how sound waves work)...or it might be louder than you think (because of how...

Everyone has that friend who loves records and insists that analog music is superior to digital. But is that true? Hosted by: Hank Green (he/him) Correction: Although this graphic can be found in many seemingly reputable sources, we've...

Sound waves vibrate more than just our eardrums, they can also make visual art!

Upon viewing the What is Sound video series, students will be able to do the following: Understand that sound is produced when matter vibrates. Explain that sound energy can travel through air, liquids, and solids, which are generally...

Space is full of radio waves, plasma waves, magnetic waves, gravitational waves, and shock waves, all of which can travel in space without a medium. These waves are recorded by instruments that can sense these waves, and the data is...

If a tree falls in a forest and no one is around to hear it, does it make a sound? Philosopher George Berkeley asked this famous question in 1710, and people are still debating it. Where is the forest located. How is sound defined? What...

Sounds can change as they move from one medium to another. Under the right circumstances the effect is surprising and extreme. Physics - Waves - Learning Points. Sound is a wave that is created by vibrating objects. Every object has a...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...

How a unique but simple experiment in the 19th century gave a new insight into the behaviour of sound waves. Physics - Waves - Learning Points. The Doppler Effect is when the pitch of a sound seems to change as it moves past. The...

This is a lecture video explaining how loudspeakers work by utilizing the motor effect, which is when a current-carrying conductor experiences a force when placed in a magnetic field. The video demonstrates this effect on a conductor...

Many ancient sites had some truly amazing effects on sound waves, suggesting that early cultures may have built spaces to evoke certain sensation. And by studying the acoustics of these structures, we can learn new things about the...
