About this Simulation

This interactive applet models the propagation of electromagnetic waves, allowing learners to observe how electric and magnetic fields oscillate perpendicular to the direction of travel. Students can adjust parameters including wave amplitude, frequency, and zoom level to explore how these variables affect wave behaviour and visualise the relationship between E and B field components.

Learning objectives: Understand the oscillatory nature of electromagnetic fields and their perpendicular relationship | Investigate how wavelength and amplitude affect electromagnetic wave properties | Visualise the 3D structure of EM waves and explain light as a transverse wave phenomenon
