| 11. | The CZCS used a rotating plane mirror at a 45 degree angle to the optic axis of a Cassegrain telescope.
|
| 12. | Large-aperture optics, however, are tested with a null corrector avoiding the production of a large plane mirror.
|
| 13. | Similar to this is the hemispherical cavity, with one plane mirror and one mirror of curvature equal to the cavity length.
|
| 14. | On this basis, he was able to define the fixed relation between an object and its image in a plane mirror.
|
| 15. | "Spiegel im Spiegel " in parallel plane mirrors : the tonic triads are endlessly repeated with small variations as if reflected back and forth.
|
| 16. | If a person is reflected in a plane mirror, the image of his right hand appears to be the left hand of the image.
|
| 17. | When space is defined this way, it becomes pictured as the the Cube that physically corresponds to the plane mirrors that trap light or time.
|
| 18. | A plane mirror makes an image of objects in front of it; these images appear to be behind the plane in which the mirror lies.
|
| 19. | If you know how fast the mirror is spinning and the distance to the plane mirror and such-you can figure out the speed of light.
|
| 20. | Commonly, a pair of curved mirrors form one or more confocal sections, with the rest of the cavity being quasi-collimated and using plane mirrors.
