For example, a “50% neutral density filter” would cut the intensity of transmitted light in half, without favoring one color over another and without making any brighter or dimmer patches. A neutral density filter would make a good lens for untinted sunglasses. – rob ♦ littlecote drive b23

"WebApr 10, 2015 · It is actually just a convention that the phase change happens on reflection from an optically denser medium. The actual requirement is more subtle and comes from energy conservation. To see this, consider a black box optical system which you know nothing about except that no energy is lost inside.

WebApr 8, 2024 · The extent to which any optically dense medium bends transmitted light rays towards or away from the normal is called the optical density. The light passing via an optically dense medium bends towards the normal and if the same light passes via any rarer medium such as air, it bends away from the normal. Optical Density. Now, let us … WebDec 17, 2024 · We also know that light exhibits the properties of a wave and when a wavefront enters a new medium at an angle, it will change directions. If the light is entering a more optically dense medium, the light bends toward the normal line. If the light is entering a less optically dense medium, the light will bend away from the normal line.
