... strategy improvement. Finally, Sec. 5.4 brings the paper to a close. Methodology The proposed method takes into account heliostat optical performance deviations caused by physical deformation. Variations in facet focal lengths and rotation angles can be used to describe such deviations. To calculate...

...-explanations of the worked-out examples, the students enhanced their incomplete understandings of the focal principles, in that their self-explanations went beyond articulating existing knowledge to constructing new knowledge, as they filled in the gaps in their understanding (i.e., the definition...

... have made it abundantly clear that a defining feature of interactive physics classes is the greater extent that formative assessment is carried out during instruction. To demonstrate this focal point, we synthesize from the literature a theoretical basis for formative assessment and propose...

... of geometrical optics is sufficient; in other cases, the two models must be used together. The three problems investigated were the diffraction pattern of an object on the focal plane of a lens, a diffracting object and its image and enlarge fringes of interference with a lens. The analysis of the three problems...

... of the James Webb Space Telescope one million miles away from Earth and to ask internet search engines for “espresso near me.” The principle of relativity, articulated by Galileo and refined by Einstein, connects in profound ways to nearly all theoretical frameworks in physics, making it a focal target...

..., attaching meritocratic values to racial categories, creating differential outcomes based on people's identities, exerting control over people's social standing, and limiting people's agency to engage in mutuality. Their analysis shows the center and margins to be reproduced in several features of the focal...

... is called the detector circle (Fig. 3.1 ). Placing the center of our detector at this focal point will allow the sharpest diffraction peaks to be observed. FIG. 3.1 Schematic showing common geometries for diffractometer instrumentation, such as (a) Bragg–Brentano and (b) Debye–Scherrer. Typical optics...

... resection of brain tissue responsible for seizures may benefit patients with medication-resistant focal epilepsy. When non-invasive electrophysiology fails to locate the boundary of this tissue, invasive techniques are considered. Intracranial EEG (iEEG) involves placing electrode arrays on the cortical...

... of thickness 1 cm, filled by liquid CS₂. In the focal plane, the beam’s waist was ≈16 μm, and the respective Rayleigh (diffraction) length (RL) was ≈1 mm. As it might be expected, the increase of the power of the incident beam leads to a transition from the linear propagation, dominated...

... . This distance f of ray intersection is the focal distance of the lens. In 1647, Cavalieri further linked f to the radius of curvatures R₁ and R₂ of the lens on both sides, the thickness t_d of the lens, and the refractive index...
