About this Simulation

This simulator models Bragg's law for first-order diffraction (n=1), allowing students to explore how X-rays interact with crystal planes. Adjust wavelength, crystal spacing, and incident angles to observe how diffraction conditions are satisfied and visualise the resulting interference patterns in real time.

Learning objectives: Understand the relationship between wavelength, crystal spacing, and diffraction angle in Bragg's law | Predict when constructive interference occurs for X-ray diffraction | Investigate how crystal structure affects diffraction patterns
