when the object is said to be completely transparent to radiation
Answers
Explanation:
in the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. On a macroscopic scale (one where the dimensions investigated are much larger than the wavelength of the photons in question), the photons can be said to follow Snell's Law. Translucency (also called translucence or translucidity) allows light to pass through, but does not necessarily (again, on the macroscopic scale) follow Snell's law; the photons can be scattered at either of the two interfaces, or internally, where there is a change in index of refraction. In other words, a translucent material is made up of components with different indices of refraction. A transparent material is made up of components with a uniform index of refraction.[1] Transparent materials appear clear, with the overall appearance of one color, or any combination leading up to a brilliant spectrum of every color. The opposite property of translucency is opacity.
Answer:
When a light wave strikes the surface of an object, a variety of things can happen. One of these things is called resonance. When resonance occurs between a light wave and an object, the object absorbs the energy of that light wave. The light energy stays inside the object when resonance occurs, but what about when resonance does not occur? What happens to light waves that are reflected off the object or transmitted through the object? In this lesson, we're going to study light waves a little further in order to understand transparency and opacity
