In this learning episode, from the Institute of Physics, students use experimental techniques and modelling to investigate simple harmonic motion (SHM). The activities include discussions, practical investigations and worked examples, including: • linking Hooke's law and SHM • investigating a loaded spring...

In this learning episode, from the Institute of Physics, students investigate the simple harmonic motion of a pendulum. This involves discussion and student investigations. The activities include: • measuring the restoring force • investigating the time period of a pendulum • using a computer model of a pendulum •...

Produced by the Institute of Physics, this learning episode enables students to appreciate that there is a continuous interchange between potential and kinetic energy during simple harmonic motion. Students are also shown the mathematical basis for calculating energy.

The activities include:
•...

From the Institute of Physics, this learning episode will help students to see how energy moves from an oscillating system and how this results in a decrease in amplitude that follows an exponential decay pattern.

The activities include:
• observing water oscillating in a u-tube
• the motion of...

In this learning episode, from the Institute of Physics, students see demonstrations and perform practical work to understand how simple harmonic oscillators show resonance when forced to vibrate at their natural frequency.

The activities include:
• discussing resonance
• demonstrating Barton's...

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: ...

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 •...

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...

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...

This series of resources, produced by the Institute of Physics, develops the idea that there are several types of electromagnetic radiation, similar to light, all of which travel at the same speed in empty space. The topic is split into learning episodes which are self-contained activities that take one or two...

This learning episode, from the Institute of Physics, help students to develop their idea of electromagnetic radiation and polarisation. The basic ideas are developed through demonstrations and experiments. The approach is non-mathematical. The activities include: * using polarising filters to observe polarisation...

In this learning episode from the Institute of Physics, through a demonstration and the production of a presentation, students extend their understanding of the nature of different types of electromagnetic radiation, and considers their shared nature.

The activities look at:
• using heat detector and...

In this learning episode, produced by the Institute of Physics, students investigate how the intensity of radiation decreases with distance from the source.

The activities include:
* demonstration and discussion on how radiation spreads
* worked example to illustrate thinking in proportions...

These activities, from the Institute of Physics, give an overview of reflection and refraction. The emphasis is on an interpretation in terms of waves. Applications, particularly those involving total internal reflection, are considered.

The series of learning episodes include:

Episode 317:...

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'...
