Physics · Light & Optics
A logarithmic ruler running from radio waves to gamma rays. Students read wavelength, frequency and photon energy together alongside the observing instruments, everyday objects at that scale and real applications for each band. The full interactive is available to licensed Education Universe users.
Ask students to place everyday technologies on the spectrum before checking the ruler.
Start a free 30-day trial with class codes and progress tracking, or talk to us about your school's licence.

A 2D and 3D optical lightbench for mirrors, lenses, refraction, total internal reflection and real and virtual images. Students arrange components and trace rays to see…
Students use a ray-based light model to compare sharp and soft shadows, investigate umbra and penumbra, move the Moon through solar and lunar eclipse geometries, and…
Explore single-slit diffraction and the transition from a wave-based description to a geometric-ray approximation. Students adjust wavelength, slit width and distances…
Mixed questions covering acceleration, deceleration, initial and final velocity, elapsed time and the conceptual difference between speed and acceleration, with worked…
Students explore initial velocity, final velocity, elapsed time and the resulting acceleration through animated motion paired with a velocity-time graph, comparing…
Electromagnetic Spectrum Ruler is one of the licensed interactives in The Education Universe. This page describes it; teachers use it in lessons and classes with a licence or the free trial.
