WebThe high optical density of diamond (n = 2.4) defines a significant energy loss in Fresnel reflection (up to 30% for a plane-parallel plate). Consequently, the actual problem is to decrease the Fresnel losses of the optical elements of this material. WebInitial optical density 1 0.5 FIG. 2. Relationship between the increment factor of optical density per LDC and the initial optical density (i.e. at the onset of the light period) of Scenedesmus 276---3a grown in culture tubes ((3) or in a rocking-tray vessel (x). Values are means of two to four in- dependent measurements.

WebSee Answer. Question: Question 6 O /1 Points Optical density is a measure of the refractive index. Higher optical density implies a higher refractive index. What happens to the speed of light when light enters a medium of higher optical density from a medium of lower optical density? A. The speed of light is higher in the second medium than in ... WebThe maximum optical density that can be achieved with a given film depends only on the amount of silver halide in the original emulsion as this determines how much silver can be formed on development. This can be seen to increase the sensitivity of the film as well (Figs 5.5, 5.6) as the response curve is made steeper.
