Teaching Advanced Physics: Vibrations and Waves

From the Institute of Physics, these resources are split into topics and each topic is subdivided into a number of episodes. An episode represents a coherent section of teaching – perhaps one or two lessons. The topics covered are:

* Simple harmonic motion
* Progressive waves
* Electromagnetic waves
* Reflection and refraction
* Superposition

Episode 308: Preparation for the Progressive Waves Topic

In these activities, from the Institute of Physics, students look at waves, speed, frequency, wavelength and wave graphs. They provide an opportunity to assess and build on prior knowledge.

In this topic, there are three learning episodes:

Episode 309: ...

Episode 309: Generating 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 •...

Episode 310: Wave Graphs

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...

Episode 311: Speed, Frequency and Wavelength

These activities, from the Institute of Physics, consider how speed, frequency and wavelength are linked by the wave equation v = fλ . This is achieved by measuring frequency using an oscilloscope and measuring the velocity of sound in free air.

The activities include:
* worked example to deduce and...
