ANSWER KEY 1 diffuse scattering When light is reflected off a surface in all directions. 2  dispersion Spreading out of the different wavelengths of light, caused by refraction of light as it passes through a prism. 3  frequency The number of waves produced each second.4  The unit of frequency is hertz, 'Hz'.n the ray diagram: 1  the hatched vertical line on the right represents the mirror. 2  the dashed line is called the normal, drawn at 90° to the surface of the mirror. 3  the angle of incidence, i, is the angle between the normal and incident ray. 4  the angle of reflection, r, is the angle between the normal and reflected ray.

Scattering In the air, part of the sunlight is scattered. The small particles (molecules, tiny water droplets and dust particles) scatter photons the more, the shorter their wavelength is.Therefore, in the scattered light, the short wavelengths predominate, the sky appears blue, while direct sunlight is somewhat yellowish, or even reddish when the sun is very low.hus, if the scattering particles are larger than the wavelengths of light, the light is scattered much more, but long and short waves are affected equally. In bulk (nonabsorbing) matter of constant density, the scattered waves cancel each other in all directions except the direction of propagation.

Flash Diffuser - Lambency Flash Diffuser - Lambency. Also known as a Lightsphere. A lambency flash diffuser is a device that fits onto the front of a flash and both reflects and diffuses the light output, reducing greatly shadows. The flash unit is pointed vertically, and the device fitted, light hits the curved top cap of the unit and this reflects it back through the side.

Energy: The Driver of Climate Scattering of solar radiation occurs when the radiation strikes very small objects in Earth's atmosphere, such as air molecules, tiny water droplets, ice crystals, or aerosols (tiny airborne particles), which disperse the solar radiation in all directions.

Dispersion Dispersion. Diserpsion is the temporal spreading of a pulse in an optical waveguide (an optical fiber, for instance). Dispersion is what causes a wave to separate into spectral components with different wavelengths.There are three types of dispersion: chromatic, modal or waveguide.1  Chromatic dispersion.2  Also called material dispersion, occurs from a frequency-dependent response of material to waves.ispersion is what causes a wave to separate into spectral components with different wavelengths.

CEREBRAL CONTUSIONS, DIFFUSE AXONAL INJURY, AND THE SHAKEN BABY SYNDROME DIFFUSE AXONAL INJURY (TRRAUMATIC AXONAL INJURY). Diffuse axonal injury (DAI) is a special traumatic lesion, which occurs most frequently in motor vehicle accidents and following blows to the unsupported head. In the course of such injuries, the cerebrum goes into a back and forth gliding motion, pivoting around the upper brainstem.

- What Is Simple Diffusion? In a solution or gas that has an area of high numbers of particles and an area of lower numbers of particles, the particles will diffuse, or move, from the area of higher to the area of lower concentration. This is known as simple diffusion, or passive diffusion. Simple diffusion does not require energy. Instead, it happens by random motion. Random motion is defined as movement that occurs by chance because there is no order or regular system by which the movements of the particles shift in a solution or gas.

Rayleigh scattering The particle therefore becomes a small radiating dipole whose radiation we see as scattered light. Rayleigh scattering of sunlight in the atmosphere causes diffuse sky radiation, which is the reason for the blue color of the sky and the yellow tone of the sun itself.

- Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection. surface may also exhibit both specular and diffuse reflection, as is the case, for example, of glossy paints as used in home painting, which give also a fraction of specular reflection, while matte paints give almost exclusively diffuse reflection.

Facilitated diffusion Diffusion refers to the net movement of molecules from higher to lower concentration. Diffusion may be a simple diffusion or . A simple diffusion is one in which that occurs unassisted. Facilitated diffusion in contrast is an assisted diffusion in a way that it requires a carrier molecule. For instance, polar molecules diffuse across a cell membrane through carrier molecules in the cell membrane.

- Diffusion, also known as migration, is the scientific name for the intermingling, or mixing, of the atoms, molecules or ions of two different substances in contact with each other. The substances can be gases, liquids or solids, and diffusion is the result of random thermal motion of their particles.he particles of a substance are in continuous, random motion in every direction, but there is a net flow of particles down the diffusion gradient or, in other words, from the area of higher concentration to the area of lower concentration.

Diffuse reflection In real life terms what this means is that light is reflected off non-shiny surfaces such as the ground, walls, or fabric, to reach areas not directly in view of a light source. If the diffuse surface is colored, the reflected light is also colored, resulting in similar coloration of surrounding objects. surface may also exhibit both specular and diffuse reflection, as is the case, for example, of glossy paints as used in home painting, which give also a fraction of specular reflection, while matte paints give almost exclusively diffuse reflection.

scattering See sprinkle. 2. Scatter, dispel, disperse, dissipate imply separating and driving something away so that its original form disappears. To scatter is to separate something tangible into parts at random, and drive these in different directions: The wind scattered leaves all over the lawn.

Solar And Terrestrial Radiation The process by which aerosols and molecules disperse radiation in all directions. Scattering is a function of the wavelength of the incident radiation and the size, surface, and composition of the scattering aerosol or molecule where size is defined relative to wavelength.

- Specular and Diffuse Reflection. The amount of light reflected by an object, and how it is reflected, is highly dependent upon the smoothness or texture of the surface. When surface imperfections are smaller than the wavelength of the incident light (as in the case of a mirror), virtually all of the light is reflected equally.

Brownian motion Brownian motion or pedesis is the random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid. This pattern of motion typically alternates random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume. This pattern describes a fluid at thermal equilibrium, defined by a given temperature. Within such fluid th
