Candlelight Diffraction on CD - Physics of Light in Action #2141067 (License: Personal Use)

A white paraffin candle burns steadily at the center, its flame illuminating a compact disc positioned just behind it. The CD’s microscopic grooves act as a diffraction grating, splitting the flame’s light into brilliant concentric rainbow arcs visible on either side. The stark black background enhances contrast, making the spectral bands-red, orange, yellow, green, blue, indigo, violet-pop with scientific elegance.
