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 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'...

Produced by the Institute of Physics, this learning episode introduce students to electric fields, field lines and equipotentials. Similarities with gravitational fields are highlighted, but with the need to take account of the of charge.

The activities include:

* exchange particles
* interactions...

From the Institute of Physics, this learning episode encourages students to investigate the quark model, which creates relative order out of the chaos of particle classification.

Quarks have three ‘colour’ charges, and the rule for stability is that combinations must be colourless.
