👉 A non-rayed object is an object that does not have a visible light source. Non-rayed objects can be either transparent or opaque, and they may also reflect or refract light in specific directions. Non-rayed objects are often used to demonstrate the principles of optics, such as the interference and diffraction phenomena, by creating images or patterns on surfaces without any external illumination. They can also be used for testing the properties of materials that do not have a visible light source, like those found
