Scene 2: Light Spectrum & Tissue Penetration combines two fundamental concepts in a single immersive experience. Students first visualize red and near-infrared (NIR) light waves (600-700nm and 700-1100nm) within the electromagnetic spectrum, comparing these therapeutic wavelengths to other colors of light. They then observe how these wavelengths interact with the layered structure of skin, fat, and muscle, watching light navigate biological barriers to reach deep tissues. The AR environment displays two side-by-side diagrams: the spectrum showing highlighted therapeutic wavelengths, and a tissue cross-section demonstrating that UV and blue light stop at the surface while red and NIR photons travel deep into muscle tissue.

By observing how different wavelengths behave, learners gain an intuitive understanding of the physical properties that make PBM effective, bridging the gap between physics and biology in a way that traditional diagrams cannot convey.

This interactive exploration emphasizes the pathway that photons take, showing that the body's surface is not a static barrier but a dynamic medium that influences therapeutic outcomes.
