For our third quantum problem we will visit harmonic oscillators. In a classical setting, this is like the ball on a spring we examined when learning about Hooke's law in the classical physics series. But this has quantum application as...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

The equation for the harmonic frequencies of stringed instruments is derived. Harmonic numbers and fundamental frequency are defined. A guitar is used to demonstrate harmonic numbers.

The video explains the concept of frequency and pitch in sounds. The video gives examples of different sounds with varying frequencies and explains how they are perceived as high or low pitch.

In this video, students learn how to subtract fractions to solve word problems using data presented in a line plot. The video explains the process of subtracting fractions with common denominators and uncommon denominators, and...

You're as blind as a bat! Well, that's not so bad, it turns out. Why? Because bats use this amazing talent they have, called 'echolocation'. It's sort of like a natural sonar. To help us explain this strange phenomenon, we have Margot...

One may have heard about Raman effect quite a lot of times. In this...

This nugget explains the parameters and mathematical derivations of a progressive wave, like amplitude, wavelength, frequency, phase, etc.

It introduces the concept of statistics. It explains statistical data and its representation and frequency.

Development of Quantum Mechanics: Photoelectric Effect Example 1

In this video, the teacher explains how to create a line plot to display the growth in inches of each student in a class over summer break. The teacher demonstrates how to create common denominators and convert fractions to equivalent...

Powerful statistical analysis tools are available in the Excel is add-in data analysis package. This is an example of generating a randomly sampled Poisson distribution (1000 values) and plotting the frequency of the result.

In this video, we’re going to look at frequency tables.These numbers are enough to give someone a headache and there's only 200 of them. `Lot's of datasets have thousands of even millions of pieces of data so, we need to collect and...

In this video, the concept of probability is explained using the example of flipping a coin. Theoretical and empirical probability are discussed and compared. The video emphasizes the importance of comparing theoretical and empirical...

The equations for the harmonic frequencies of open and closed pipe wind instruments are derived. An animation of a longitudinal standing wave pattern in a closed pipe is shown. Displacement and pressure nodes and antinodes are shown.

So Max Planck kicked things off, but how does the story of modern physics continue? With none other than your favorite scientist and mine, Albert Einstein! He did more than just stick his tongue out and have crazy hair. He elucidated the...

Use physics to create cool patterns on a vibrating plate. How is this like a guitar string or a singing wine glass?

This video is a tutorial on frequency and two-way tables. The presenter explains how to collect data on a specific variable and convert it into a frequency table. They also introduce the concept of relative frequency and how to use it to...

The range of human hearing is 20Hz to 20,000Hz. Ultrasound waves are just sound waves with a frequency above 20,000Hz. When ultrasound reaches a boundary between two media with different densities, some are partially reflected back and...

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...

The video discusses the concept of light as a type of electromagnetic radiation and explains the different types of radiations in the electromagnetic spectrum based on their wavelength, frequency, and energy. It also highlights the...

Create a frequency table and a dot plot to display data.
