👉 Diaphanometry is a measurement technique used in optics and astronomy, where light rays are bent or refracted by various materials. The phenomenon of light bending can be explained using the principle of refraction, which states that light travels in a straight line when it passes through an obstacle (like air), but bends slightly as it enters an optical medium with varying density, such as a liquid. The technique is named after the Greek philosopher Diophantus, who described it in his work "On
