👉 Unrefractiveness is a phenomenon in optics where light cannot be refracted back towards its original direction. This property is often associated with materials like glass, which has a very high index of refraction and therefore can transmit light without bending it. The concept of "unrefractive" refers to the fact that light can't bend around objects or surfaces, including the ones made of glass, due to the high refractive index of these materials. This property is essential for our understanding of
