👉 In physics, "unshading" refers to a phenomenon where light rays are blocked from reaching a point due to an obstruction or interference. This can happen when there is a difference in refractive index between two media (like air and glass) or when a material has a significant thickness or density that interferes with the path of light. For example, imagine a streetlight on a sunny day where you are standing at one end of it and looking out the other. If you move to another
