Learn all about Waves, the Electromagnetic Spectrum and Light with these new Notebook Pages and Worksheets!
In this section, we went over terms like wavelength, frequency and amplitude before talking about the 7 types of electromagnetic waves in the electromagnetic spectrum
- radio waves
- infrared radiation
- visible light
- ultraviolet radiation
- gamma rays
The electromagnetic spectrum is the range of wavelengths or frequencies over which electromagnetic radiation extends.
We talked about what some of these different types of waves are used for. For example, microwaves are not only used for cooking but are also used in modern technology for point-to-point communication links, wireless networks satellite and spacecraft communication, medical diathermy and cancer treatment, air-traffic control and more.
From there we went on to talk about light & the human eye. We talked about how the different parts of your eyes work together to help you see. We talked about the cornea, pupil, iris, retina and the way photo-receptors (rods and cones) work.
I also included a couple of pages that goes into a bit more detail about the wave nature of light. I used this page with my high schooler (who went on to do some calculations using the formula c = λ ν

Our 100+page Energy Packet covers a range of topics from energy and force, kinetic and potential energy, the types and sources of energy, power grids, to fossil fuels, the carbon cycle and more! You can find out more about this packet here at this page: Energy Unit – Kinetic vs Potential Energy, Renewable vs Non-renewable Energy, the Carbon Cycle and More! I will also include more pictures down below!
What age/grade is this energy unit for? We covered this material in middle school. My daughter was in 6th grade (age 12) last year and my other daughter was in 9th grade (age 14). We covered the section on light this year when my daughter was in 7th grade (still age 12) and my other daughter was in 10th grade (age 15).
The 100+-page Energy Packet is $7.99. This is a pdf download.
The Energy Unit is included in the Earth Science & Physical Science BUNDLE of 10!
