The electromagnetic spectrum

taught by Math Arena

Course description


This course is targeted at Singapore Cambridge GCE O level students, but is also relevant to IGCSE students and Singapore's Integrated program students.

If you've ever seen a rainbow before, you know that light can be split into different colours. But that's really just the beginning of it. The light that we know and see is just a small fraction of the vast electromagnetic spectrum comprising anything from radio waves to infrared rays to X rays and gamma rays.

Course Content

You will learn:

  • What the different types of electromagnetic waves are and their properties
  • Interesting uses of electromagnetic waves
  • Why some electromagnetic waves go through walls and others can't
  • Why your car gets so insanely hot when you leave it in the sun
  • Why you should not use gamma rays for pre-natal scanning
  • Other cool stuff! (Some of the videos in this course are marked as "explanation videos", which go into greater depth on the topics covered. We try to bring in out-of-syllabus concepts where possible to make things more interesting and give a more complete understanding of the topic)

Course Prerequisites

You will need to know:

  • Some concepts from heat transfer (conduction, convection and radiation) and waves (v=fλ) which will be touched on in some questions
  • How to watch videos on your computer
