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.

In this video, we are going to look at a way of presenting data: The Histogram. There are lots of misconceptions about histograms and we will try and clear up some of these along the way.

Sympathetic vibrations are demonstrated using pendulums of various lengths and a guitar.

In this video, the teacher explains how to determine if rolling a die will result in an approximately normal distribution. They use visualizations to show the characteristics of a normal distribution, such as a symmetric, bell-shaped...

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,...

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...

This video provides an explanation of histograms, which are a type of bar chart used for grouped data. The key differences between histograms and regular bar charts are explained, such as the use of frequency density on the y-axis and...

This video reviews what harmonic motion is then provides definitions of all the components of the wave. Real world examples of simple harmonic motion are shown. Students will learn how to calculate frequency using a pendulum and a spring.

The video talks about frequency diagrams and histograms as graphical representations of frequency data that is grouped into intervals. The speaker explains how to plot a frequency polygon and a histogram and calculates the frequency...

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.

In this video, we are going to look at how we can find the mean from data in a table. A mean is commonly associated with the term average and is found by dividing the sum total of values by the number of values themselves.

Check out the range of possibilities the electromagnetic spectrum gives science. This animated series of short videos acts as a video glossary to define specific scientific terms or concepts in a fun, easy to understand way. In each...

This video explains how to construct and interpret frequency tables. It starts by defining what frequency means and how frequency tables work. The video provides an example of a survey where Jenny asked her friends about their favorite...

Electrical supplies can be direct current or alternating current. It's referred to as AC/DC but not rock band of course. If the current flows in one direction it is called direct current. Batteries supply DC current to most of your...

This is an introductory video to Albert Einstein's photoelectric effect, the discipline that made him a Nobel laureate. <br/>
-For Physical chemistry & Quantum le<br/>vel studies

This video introduces the concept of overtone singing, a technique used by trained vocalists to sing more than one note at a time. It explains how voice is produced and the role of vocal cords, and then delves into the production of...

This nugget briefly explains periodic motion, displacement in periodic motion and its units

If you sing at a wine glass at its exact resonant frequency, you can break the glass without the help of a speaker! Learn the physics behind that.

Helping children relate to the topics they study is what the Real World Science series of videos does best. Real World Science: Sound helps students learn the principles of sound, the range of human hearing and significant terms, as they...

Using real world demonstrations and colorful graphics, Real World Science: Light teaches students the different properties of light, pertinent definitions and how light travels. Students will learn how different mediums can affect light,...

"The Ear

The visible part of the ear is called the pinna. It funnels sound into our e

ars.

The sound waves travel down the ear canal toward
s the eardrum.
The eardrum is a membrane at the end of the ear...

This video engages students by asking questions and showing phenomena that relate to simple harmonic motion. The program provides examples and demonstrations using “singing” glasses, violin and piano sounding boards, oscillations in...
