Many demos are suggested using many different types of wave motion. The first time you set these up keep diagrams or exact...

Teaching Guidance 16-19

There are some experiments which must be done in semi-darkness, for example, optics experiments and ripple tanks. You need to...

Teaching Guidance 14-16

There are many excellent applets available online that show wave behaviour as if observing a ripple tank or oscilloscope...

Teaching Guidance 14-16

Given some radiation, how can one tell whether or not it has wave properties? Superposition experiments offer an answer. Radio...

In water whose depth is large compared to the wavelength, the wave speed expression contains two terms, one for gravity...

Teaching Guidance 11-14 14-16

Students should whenever possible experience and experiment for themselves using real equipment, rather than using software...

Teaching Guidance 14-16

Some basic ideas about waves can be demonstrated using mechanical waves along strings or springs, ripples on water, or special...

Teaching Guidance 14-16

This episode starts by thinking about what happens when two trains of waves meet one another.

Teaching Guidance 14-16

Two waves interacting: it is essential to know about the starting conditions

Teaching Guidance 14-16

From a teaching and learning point of view it is well worth the time and effort to introduce new terms carefully.

Teaching Guidance 14-16

There is a long tradition of starting with water waves when teaching about waves and radiation in physics. This makes a lot of...

Teaching Guidance 14-16

In our experience, students often confuse the terms, refraction and diffraction . With this in mind it's useful to practice...
