S104 Book 3

This book is called Energy and Light and as the title suggests it's a physics book.

The book starts by looking at energy in various guises. It introduces the concept of kinetic and potential energies and shows how they can be used.

Then it looks at internal energy, temperature and heat transfer.

The book then moves onto electrical energy, looking at connductors, insulators and electron volts.

We then consider the energy of the sun, nuclear fusion and how what light consists of.

Finally the book considers the wave-particle duality of light.


There is an associated experiment with this book. It involves calculating the wavelength and energy of light emitted by an energy-saving lightbulb using the diffraction grating from the home kit. I enjoyed this experiment, although it was a bit fiddly I was happy with my results.

I really enjoyed studying this book. It covers some fascinating topics in a very accessible way.
