Lloyd's Mirror

Lloyd's Mirror is a phenomenon in optics where a light source near a reflective surface, like a mirror, creates an interference pattern of bright and dark fringes. This occurs because light rays directly from the source and those reflected off the mirror overlap and interfere with each other. The resulting pattern reveals information about the light's wavelength and coherence. It’s commonly used in experiments to study wave behavior and measure light properties, illustrating how light behaves both as a wave and a particle.
