Lighting is by far the most important factor when photographing glass, since the wrong setup can create out-of-control reflections or washed out blurs.
222, 223 Among many examples of structural colors, some aquatic species like cephalopods exhibit actively-tunable structural colors by controlling reflection and absorption as well as variation of their body surface texture.
The most challenging problem is to formulate materials in which the transmission of light, or, more generally, electromagnetic radiation, can be performed dynamically and independently for different spectral bands, preferably by controlling reflection (as opposed to absorption).
The principles of room design are explored including standing waves, bass control, audible reflections, flutter echo, reverberation, diffusion, imaging, noise control, noise isolation, and flanking.
The sources contributing to the absolute uncertainty of the average dosimetry were a) antenna modeling; 0.1 dB (experimentally verified); b) deviation of incident field exposure with respect to the target field including transfer calibration, sensor linearity, feedback control, and reflections from furniture, 0.7 dB; and c) average anatomy, dielectric parameters, and discretizations.
The reflected electrons suffer similar spin rotations accompanied by the reversal of the momentum p x. Interestingly, the gate voltage can be used to control the reflection and transmission, and therefore tune the spin polarization of the reflected and transmitted electrons.

These nanostructured materials can provide wavelength-selective control of reflection, absorption and transmission of light as well as angular selectivity for directional control, making it possible to design houses that have very large windows and skylights, but which nevertheless remain cool in summer and warm in winter.
Action control and reflection The participants controlled the effects of their performed actions and evaluated their success with reference to the defined goals or subgoals.
For problem-solving activities including information seeking, information recording, forecasting and planning, performing goal-oriented actions and operations, and action control and reflection, no significant effects were found.
