There are 6 lessons in this physics tutorial covering Features of Light. The tutorial starts with an introduction to Features of Light and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Features of Light. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • What are rays? What are beams? Where do they differ from each other?
  • How does light propagate?
  • Why light is an EM wave?
  • What are the main components of an EM wave?
  • Which are the colours of visible spectrum of light? How are they determined?
  • How many types of materials are there concerning their ability to allow light pass through them?
  • What is shadow? Which are the conditions for the shadow to produce?
  • What are the sub-categories of shadow? What are their features?

Introduction to Features of Light

What shape do the light beams have? Do they contradict what you already know about the shape of EM waves whose part is visible light? Explain your opinion.

Do you think all colours of light have the same features (wavelength, frequency, speed, etc.)? Why?

Are we able to see all possible light rays emitted by the Sun? Why?

Do you like to expose yourself in direct sunlight during a very hot day? What do you do in this case?

The above questions will be discussed in this tutorial, in which a number of light features will be discussed. This is done to emphasize the visible light as the part of EM spectrum that is closer to our needs.
