Waves 5 - Refraction

In this episode, we look at kinetic energy, including what it is, what is depends on, and the relationships between the energy and its dependencies.

In this episode we cover the eight energy stores and the ways energy can be transferred between them.

In this episode we explore some of the ways that waves are used to explore the world around us. From foetus scans and sonar to the structure of the Earth, waves can give us information about things that we would otherwise know very little about.

In this episode we discuss sound in more detail, including a comparison of how sound travels through different states of matter, what a sound wave does when it comes into contact with a new medium, and how this all relates to human hearing.

In this episode we discuss what happens to a light ray as it passes through a glass block at different angles.

In this episode we discuss specular and diffuse reflection and the law of reflection for light.

In this episode we will look at how we can measure the speed of waves in air, water, and string.

In this episode we go through some of the terminology used to describe the properties of waves, such as wavelength and amplitude. We also discuss the link between time period and frequency, and the wave speed equation.

In this episode we go through the two categories of wave, transverse and longitudinal. We discuss the features of each and their identifying properties.
