Geometrical optics approximation is a classic method for calculating the optical trapping force on particles whose sizes are larger than the wavelength of the trapping light. In this study, the effect of the lens misalignment on optical force was analyzed in the geometrical optics regime. We used geometrical optics to analyze the influence of off-axis placement and the tilt of the lens on the ... c. 1200, "that which is best," from best (adj.).

A. 60 0 D "a skate, type of fish related to sharks and noted for its broad, flat body," early 14c., raie, from Old French raie (13c.) and directly from Latin raia. De Vaan describes this as a word of unknown origin but with apparent cognates in Germanic (Middle Dutch rogghe, Old English reohhe), perhaps a loan-word from a substrate language. The old etymology (Century Dictionary, etc.) was that the fish was so called from its resemblance to the rays of a fan and from the source of ray (n.1).

Answer : Laws of Refraction : 1 ) The incident ray, point of incidence, normal and refracted ray of light are coplanar. 2 ) The ratio of sine of angle of incidence and angle of refraction is constant. ( This constant term is nothing but the refractive index of the medium ) i.e, sin i / sin r = constant. Where i = angle of incidence.

Useless. Answer from: jessicapbailey52. SHOW ANSWER. D.) Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection. Explanation: As per ray diagram we can see that light ray moves from one medium to another medium. So this must be the phenomenon of refraction of light.

A block is attached to the top of a spring that is oscillating vertically. A small coin with negligible mass is riding on top of the block (it is not …. attached to either the block or the spring). You measure that the largest possible time for the block to complete one full oscillation, without causing the coin to fall off, is 2.5 s.

"to get the better of, outdo, surpass," 1863, from best (adj.). Related: Bested; besting.

Here, Object AB is beyond 2F 1. First, we draw a ray parallel to principal axis. So, it passes through focus after refraction. We draw another ray which passes through Optical Center. So, the ray will go through without any deviation. Where both rays meet is point A'. And the image formed is A'B'. This image is formed between F 2 and 2F 2.

"beam of light, light emitted in a given direction from a luminous body," early 14c., rai, from Old French rai (nominative rais) "ray (of the sun), spoke (of a wheel); gush, spurt," from Latin radius "ray, spoke, staff, rod" (see radius). Not common before 17c. [OED]; of the sun, usually in reference to heat (beam being preferred for light). Ray is usually distinguished from beam, as indicating a smaller amount of light; in scientific use a beam is a collection of parallel rays. In ordinary language ray is the word usually employed when the reference is to the heat rather than the light of the sun .... [OED] Science fiction's ray-gun is recorded by 1931 (in Amazing Stories; electric ray gun as an imaginary weapon is from 1924; death-ray gun from 1926 as a prop in a vaudeville act), but the Martians had a Heat-Ray weapon in "War of the Worlds" (1898).

The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium. Alternatively, it could be said that the refractive index is the measure of the bending of a light ray when passing from one medium to another. Mathematically, it can be represented as a ratio between two different velocities - the ...

Old English beste, reduced by assimilation of -t- from earlier Old English betst "of the highest quality or standing, first, in the best manner." This originally was the superlative of bōt "remedy, reparation" (Middle English bote "advantage, help, profit"), a word now surviving in its simple form only in the expression to boot (see boot (n.2)). Its comparative, better, and superlative, best, have been transferred to good (and in some cases well). Old English bōt is from Proto-Germanic root *bat-, with comparative *batizon and superlative *batistaz. The superlative form is the source also of Old Frisian, Old Saxon, Middle Dutch best, Old High German bezzist, German best, Old Norse beztr, Gothic batists. Also in Old English as an adverb, "in the most excellent manner." The best-laid schemes o' mice an' men Gang aft agley, An' lea'e us nought but grief an' pain, For promis'd joy!

Meaning "image made using X-rays" is from 1934, earlier in this sense was X-radiograph (1899).

It will represent the path of ray inside the glass slab, i.e. refracted ray.
