...of the bush which is in shadow. The rule governing our perception of reflections is a familiar one : The angle of reflection is always equal to the angle of incidence. Practically applied to our illustration, this means that standing twenty feet above the bush and fifty...

...r, which the incident ray on the one side and the reflected ray on the other, make with the normal. The angle of reflection is always equal to the angle of incidence. A ray (pm) striking the mirror perpendicularly, is reflected into itself (toward mp). From this law...

...LIGHT That property by which a ray of light rebounds or is sent out again when it strikes an object. The angle of reflection is always equal to the angle of incidence, and they are at right angles to one .-mother, and may be likened to the action of a billiard ball when...

...reflected ray and that of the mirror. The two following laws are observed in the reflection of light : (1) The angle of reflection is always equal to the angle of incidence, and (2) the incident and the reflected rays occupy the same plane. In the figure below M is the face...

...from the wave theory of light, that in a plane mirror the reflection follows a fixed law, namely, that the angle of reflection is always equal to the angle of incidence ; that is, the angle CDP is always equal to the angle ODC. Fig. 1. Fig. 2. What is true for one ray,...

...medium, therefore if we know the index figures of the two mediums we can find where a ray will go. The angle of reflection is always equal to the angle of incidence. The ray R starts toward 1, is broken at the first surface and takes direction of 2, is broken at the...

...as the incident ray, that the line perpendicular to the mirror at that spot is the normal, and that the angle of reflection is always equal to the angle of incidence. Think of this, and you have the whole secret of the curved mirrors. In our sketch a ray parallel to...

...horizontal axes so that its surface may be at various angles to the rays of light. Observe (A) that the angle of reflection is always equal to the angle of incidence, and (B) that the incident ray, the perpendicular at the point of incidence and the reflected ray are...

...Reflection (re-flec'-shun). Throwing back light. Reflection from a plane surface gives an erect image, and the angle of reflection is always equal to the angle of incidence. The image is formed at a distance behind the '-effecting surface equa' v ci £-,tn LI i aj .3 vv 11.11/1.1...

...subject that has to be dealt with. But the work will be much simplified if it is kept in mind that the angle of reflection is always equal to the angle of incidence. If the angle be, we will say, one of 45 degrees, which, as a rule, is a suitable one for what we are...
