Interreflection Interreflection(ordiffuse interreflection) is the illumination of nearby objects, or parts of the same object, caused by their mutual diffuse reflection. Photorealism,Ray tracing,Software terms
When a light beam strikes a smooth surface, most of it reflects back in the same concentration. This is specular reflection, which gives us direct, bright light. A mirror is a common example of a smooth surface that causes specular reflection. On rough surfaces, even microscopic irregularities ...
Total integrated scattering (TIS) describes how much light is deviated (or scattered) from the incident light direction by diffuse reflection and transmission from a surface or optical element. It is equal to the ratio of diffuse reflected and transmitte
emitting a circumstellar shell of hydrogen gas. When this phase comes to an end, the star enters the PPN phase, where it is energized by a central star, causing it to emit strong infrared radiation and become a reflection nebula.
What is the Gulf Stream? What is a PCB stencil? What is the P wave shadow zone? What is the heliosphere? What heart rhythm has no P wave? What is pediment in geomorphology? What is a diffuse nebula? What is a rectilinear tidal current?
Reflection nebula: NGC 1999 Another type of diffuse nebula, a reflection nebula doesn’t emit its own light, but scatters light from embedded stars. (Image credit: NASA, JPL-Caltech, Kate Su (Steward Obs, U. Arizona) et al.) Planetary nebula: The Helix Nebula This is composed of expand...
A light ray travels in a straight line but can also curve around an obstacle and the process of curving or bending of light is known as diffraction. The condition required for diffraction is that the size of obstacle must be of the order of the wavelength of light....
An anti-glare screen is a screen that features a layer of coating that minimizes reflections. The effectiveness of an anti-glare treatment depends on its haze value and the screen surface. Glare is the reflection of light from a source (such as the sun) off of a window or a screen, mak...
Q: Is FTIR affected by the environment? Q: How deep does the infrared light penetrate at the position of contact between the prism and sample during ATR measurements? Q: What sort of sample concentration should I use for measurements by the KBr pellet method or diffuse reflection method? ...
