...according to the Nature of the Rays of all Luminous Bodies, with whom (as we are taught by Optics) the Angle of Reflection is always equal to the Angle of Incidence. Wherefore all the Rays in general being confined and refifted by the Body they would project, and having...

...the fides of the figure b, myn,p'y and A, 2, 3, 4, A, will be the path of the moving body A, becaufe the angle of reflection is always equal to the angle of incidence, and the center of the ball, perpendicular to the point of contract ; hence by drawing 2 F, 3 G and...

...that is, either perpendicularly or obliquely; and experience has proved, that when light is reflected, the angle of reflection is always equal to the angle of incidence. Thus, fuppofe ab, jig. 25, pi. i, to be the furface of a plane mirror, If a ray of light fc falls perpendicularly...

...equal to B' MP, and the angle A mw, equal to the angle B m P. Toil This property is thus enounced : The angle of reflection is always equal to the angle of incidence. I have already taken notice of this ftriking property ; but my defign, at prefent, is to fhew what the...

...without coming into contact with the matter which repels it. The ray is then said to be reflected. The angle of reflection is always equal to the angle of incidence. EXPERIMENT II. To prove that the angle of refection is equal to the angle of incidence. There are several...

...through a stratum more rare. The rays of light are likewise capable of being reflected from bodies; and the angle of reflection is always equal to the angle of incidence. A ray is said to be perfectly reflected, when the whole of it is again thrown out, either as it struck...

...anil called looking-glasses. The doctrine of mirrours depends wholly on that fundamental law, that the angle of reflection is always equal to the angle of incidence. See OPTICS. Parallel rays falling directly on a plan« speculum are reflected back upon themselves;...

...angle, equal to that formed with the same body, by the original impinging ray ; or, in other words, the angle, of reflection is always equal to the angle of incidence. Thus, if the original ray fall perpendicularly on the reflecting body, the reflected ray will return...

...elastic ball were made to strike obliquely ajcainst the ground. The ray is then said to be reflected. The angle of reflection is always equal to the angle of incidence. When a ray of light passes within a certain distance of another body, it is bent to-iciirda it ; at...
