ncert.nic.inOptical Instruments 311 this case is to be taken as normal to the tangent to surface at the point of incidence. That is, the normal is along the radius, the line joining the centre of curvature of the mirror to the point of incidence. We have already studied that the geometric centre of a spherical mirror is called its pole while

assets.thermofisher.comOptical density, however, is not a measure of absorbance, but rather a measure of the light scattered by the bacterial suspension which manifests itself as absorbance (Figure 1). The effect that the optical configuration of a spectrophotometer has on optical density measurements has been well documented (2-4). Instruments with different optical
