In this video, I talk about how the brain processes information on the different pitches that we hear. I'm warning you - it starts off a little scary, but by the end of the video, you will have a good idea of how we hear different...

How do we hear? How does sound get transferred from the ear all the way to the brain? In this video, I go into all the juicy details. Listen up and have fun.

This video explains how to use survey results to make predictions for a whole population. It uses the example of Chris surveying 80 students in a school of 300 and finding that 44 prefer chocolate ice cream.

This nugget explains the source, generation, properties and discovery of electromagnetic waves.

The Doppler Effect is demonstrated. Animations are used to show the observed change in wavelength and frequency.

Resonance Fluorescence: A Special Case of Fluorescence

This video explains how to calculate different types of averages from a frequency table, such as mean, median, mode, and range. The instructor demonstrates step-by-step how to create the fx column to find the total amount of data, and...

The video explains two important features of a wave: the frequency and the time period. It uses a visual representation of a transverse wave and a longitudinal wave to show the peaks, troughs, amplitude, and wavelength of a wave. The...

This video explains how to conduct an experiment to determine the speed of a wave on a string. It shows the steps involved, such as setting up the string or wire, creating a wave on it, and adjusting the distance between the two ends to...

This video explains how to calculate averages (mean, median, mode, and range) from a grouped frequency table. The presenter demonstrates how to estimate the mean using midpoints and frequencies, how to calculate the median using the...

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...

Wave Motion | Waves | Physics | FuseSchool All waves can transfer energy from one place to another without transferring any matter. This is done by a series of disturbances or vibrations that carry the energy. Just like the people in...

This video explains what box plots are and how to interpret and construct them. It provides specific information on the different components of a box plot, including the minimum and maximum values, quartiles, range, and median. The video...

The relationship between wavelength and frequency is determined. The number of waves, wavelength, and wave speed at each standing wave frequency is determined. The wave speed is measured independent from the standing waves.

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...

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...

Review of the Rotational Kinematics topics covered in the AP Physics 1 curriculum.

The video explains the basics of electromagnetic waves, including their definition as transverse waves that transfer energy from a source to an absorber. It discusses the seven general sections of the electromagnetic spectrum, going from...

Try to sing the impossible note! Singers try to sing into a pipe, and find certain notes are impossible to sing, even for professionals. WHY?! More facts: Most objects have a number of different resonant frequencies. The first resonance...

This video provides an introduction to the speed of sound in air and demonstrates several methods to measure or calculate it. It also presents equations to calculate the speed of sound based on the wavelength and frequency of a sound...

Appendicitis Signs & Symptoms | & Why They Occur



Appendicitis is a condition involving inflammation of the appendix. Appendicitis occurs due to blockage of the appendiceal lumen, which leads to bacterial overgrowth or...

From a tuning fork, to a speaker in slow motion, this is a close look at what sound is. Both linear and spherical wave fronts are animated. The human audible range is demonstrated.

This video is a tutorial on two-way frequency tables. The instructor explains what two-way frequency tables are and how they can provide us with two pieces of information about a data set by using two axes of the table. They use examples...

This video teaches cumulative frequency and how it is represented in a graph, specifically the less than type ogive. It uses an example of daily income of workers to demonstrate how to calculate cumulative frequency, plot it on a graph,...
