In this learning episode, from the Institute of Physics, students look at standing waves in musical instruments and measure their wavelength. Microwaves are used to estimate the speed of light.

The activities include:
* demonstrating waves in a rope
* how superposition results in standing waves...

From the Institute of Physics, this learning episode introduces the idea that vibrations can give rise to disturbances travelling outwards, i.e. to progressive waves. This illustrates some of the basic properties of waves. The activities include: • investigating transverse and longitudinal waves in a spring •...

The speed of a wave in a solid is investigated in this video. A signal generator and length of elastic are used to measure the frequency and wavelength of a wave, which allows wave speed to be calculated. 

In this video an oscilloscope simulator on a laptop is demonstrated to visualise a sound wave and calculate its frequency. 

This learning episode, from the Institute of Physics, looks at Melde's experiment. It uses the analogy of a standing wave in a stretched elastic cord before going on to introduce the idea of standing waves within an atom.

The activities include:
* Melde’s experiment
* electron waves in atoms...

This video demonstrates an investigation of reflection at a plane mirror.  This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics.

A trio of videos that investigates the refraction of light through a transparent block.  This first video allows students to see the experiment and the other two review the results and plot a graph to investigate the relationship between the incident and refracted angles.  This is a required practical for students...

This learning episode from the Institute of Physics covers the constructive and destructive interference of waves.

Through discussion, student experiments and teacher demonstrations, students look at:
* simple interference of waves
* waves from two sound sources
* demonstration of Young's...

This learning episode, from the Institute of Physics, contains activities in which students look at reflection, refraction and Snell's law.

Through discussion, demonstration and practical experiments, students look at:
* reflection and refraction with a ripple tank
* the 'marching soldiers'...

A ripple tank is used in this video to calculate the speed of a water wave by measuring the distance and time. This is a GCSE Combined Science and Physics Required Practical.

A ripple tank is used in this video to calculate the speed of a water wave by measuring the frequency and wavelength. This is a GCSE Combined Science and Physics Required Practical.

In this learning episode, from the Institute of Physics, students interpret graphs of waves to understand concepts such as wavelength, frequency and phase.

The activities in this episode include:
• plotting displacement and drawing longitudinal waves
• considering phase
• understanding...

This video explains how to measure the speed of water waves using an alternative to the ripple tank wave experiment; water in a Gratnell tray. In order to calculate the speed of a wave, we need to measure the distance covered by a wave in the time it takes to cover that distance.

Through demonstrations, discussions and worked examples, students are introduced to the phenomenon of wave-particle duality. Students learn that electrons, which are often thought of as particles, can sometimes behave as waves.

Produced by the Institute of Physics, these activities demonstrate the Doppler effect.

Using sound and microwaves, the activities illustrate how changes in wavelength of spectral lines allow us to determine the motion of astronomical objects relative to ourselves.

The activities include:
*...
