This episode considers uses of lasers, and the underlying theory of how they work.
Lesson 16-19
This episode requires students to develop their idea of electromagnetic radiation. Since they cannot see either the wave...
This episode extends students’ understanding of the nature of different types of electromagnetic radiation, and considers...
This episode considers the ways in which the intensity of radiation decreases with distance from the source.
This episode introduces the idea that vibrations can give rise to disturbances travelling outwards, i.e. to progressive waves...
Students often confuse displacement/distance graphs (from which wavelength can be deduced) with displacement/time graphs (e.g...
This episode considers how these three quantities are linked by the wave equation v = f × λ , measuring f using an...
This episode starts from the phenomenon of refraction and moves on to Snell’s law.
Total internal reflection (TIR) is a consequence of refraction.
This episode allows you to familiarise your students with the main features of simple harmonic motion (SHM), before going on...
The previous episode laid the qualitative foundations for what follows here: a mathematical approach to simple harmonic motion...
This episode and the next focus on practical simple harmonic motion (SHM) systems.
