Unit 2 - Light, Sound & Other Waves


free simulations, worksheets, videos, images, animations and more.


Lesson 2.1



Wave demonstrations & simulations, key wave terms.


Lesson 2.2





How sound waves are produced, and how they propagate.   Seeing sound waves on an oscilloscope, interpreting oscilloscope traces.



Lesson 2.3



Sound waves 2


Frequency range of human hearing.  Anatomy and workings of the human ear.


Lesson 2.4




Light waves


Luminous and non-luminous objects, spectrum of light, perceptions of colour (mach bands, chess board illusion), diffuse and specular reflection.



Lesson 2.5




Investigating reflection


diffuse and specular reflection, investigating reflection, drawing ray diagrams, law of reflection.


Lesson 2.6




Additive mixing of light


primary colours of light, adding to make secondary colours of light, making white light.


extension: seeing colours.



Lesson 2.7




Covers ideas about transmission and absorption of light through coloured filters.


Lesson 2.8

Assessment materials


Testing, target setting and more.  Coming soon.




Laser ray boxes. Awesome for demonstrating wave behaviours.



Making Galilean telescopes fits well in Unit 2 or Unit 6.



This module is currently being written and resourced; it is not complete yet.  However, there are already some great simulations, worksheets and activities you can investigate - and more is on the way.  The module will explores pupils' existing ideas about waves, and then build on this.


Students can undertake varied practical work, investigating a wide range of wave phenomena, as well as building simple Galilean and Keplerian telescopes and exploring ideas about telescope opticsThere are now some very affordable laser ray boxes which are great for illustrating these ideas.  Timstar do a great kit here (UK), or Arbor Scientific sell the same kit here (US).









Introduction to waves

Observe transverse and longitudinal waves, develop key scientific vocabulary for describing waves.


Making sounds

Allow pupils to explore the subject and lots of questions; students will likely explore ideas about producing sounds and hearing sounds in both of these lessons.   


Hearing sounds



What is light?

Key ideas about light.  ideas about luminous & non-luminous objects. 


Mixing colours

Lots of fun practical work, looking at the additive mixing of light with rayboxes. 


Seeing colours

Specular and diffuse reflections.  Subtracting colours from light.
