bundle of raysの例文
- He writes that " the recoil cannot be exactly known, since the direction of the scattered photon is undetermined within the bundle of rays entering the microscope ".
- :In the excellent book " Light and Color in the Outdoors ", by M . G . J . Minnaert, there is a section called " Bundles of rays that appear to be emitted by bright sources ".
- It says, in part, " . . . lights seem at times to cast long straight rays toward our eyes . . .; along the edge of each eyelid lachrymal moisture forms a small meniscus by which the light rays are refracted . . . . the rays are refracted at the upper eyelid in such a way that they seem to come from below; the source gets a downward tail, and the lower eyelid gives, in the same way, an upward tail . . . . The rays appear at the very moment the eyelid begins to cover the pupil; to a short-sighted observer this is easily visible, for the source of light, which he sees as a broadened disk, is at that moment partly screened off . . . . The rays are not quite parallel, not even those to one eye . . . . The reason for this is evidently that the edges of the eyelids, where they cross the pupil, are no longer horizontal, and each bundle of rays if at right angles to the edge of the eyelid that causes it . . ."
