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...

Reflection with and without inversion caused by fixed and free ends are demonstrated. Standing wave patterns at 5 different frequencies are demonstrated. A standing wave animation is shown to understand to how standing wave patterns are...

The sun is shining, the waves are rolling in, the sandy beach is calling. It’s the perfect day for finding and collecting seashells! Join in the hunt, as a little boy and his mother share a fun day of digging in the sand and exploring...

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...

It explains the concept of polarised wave with the help of activity, activity involved polaroid sheets, polarization by reflection, polarization by scatterind and brewsters law.

Deriving the velocity and acceleration equations for an object in simple harmonic motion. Uses calculus.

Demonstrating that Circular Motion, when viewed from the side, is Simple Harmonic Motion.

This is a classic experiment that is frequently referred to when describing quantum phenomena, so we definitely have to go over it a little bit. What happens when you pass a beam of light through a screen with two slits? What about when...

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.

This lecture video explains how sound waves propagate, transfer from air to a solid, and how the human ear works. The video then explains how sound waves interact with solids, including reflection, absorption, and transmission. The video...

The Spanish Flu was one of the deadliest pandemics the world has ever seen – so how was one sleepy Colorado town able to escape unscathed?

Take a look at a bubble and you’ll see all the colors of the rainbow... right? WRONG. Bubbles are actually missing colors!

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...

The equation for the speed of a wave is derived. The fact that amplitude, frequency, and wavelength do not affect wave speed is demonstrated. Two different solutions for wave speed are demonstrated.

Is it possible to hear a train coming by putting an ear to the rail track? Physics of why you can detect a train in the railway tracks from miles away.Sound is actually just a pressure wave a disturbance that's kind pushing to its...

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,...

In this episode Ill describe the uncertainty principle of quantum mechanics and talk about what it really means.

December 7, 1941 - Hawaii - Japanese spy Takeo Yoshikawa hears the code phrase “East wind, rain” on his short wave radio, signalling an attack on America. North of Oahu, Mitsuo Fuchida, Commander of the Imperial Japanese fleet, launches...

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...

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...

Why does light bend when it enters glass and how do mirages happen? Using the Huygens principle, to show why refraction will make the light bend. Also showing why Inferior mirage happens. <br/>
All this with the Huygens<br/> principle.

The 1 dimensional wave equation is solved here using the separation of variables technique (assuming u(x,t) = phi(x) q(t).



I simplify the formula further using the boundary c

onditions:


u(0,t) = 0

...

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.

This video explores five fun facts about the tsunamis.
