11. These windows are electrically switchable glass that change light transmission properties with an applied voltage. 12. However, as stated above, a superluminal phase velocity cannot be used for faster-than-light transmission of information. 13. This decrease in light transmission occurs up to the point at which critical compaction is reached. 14. This data is rated in Visible Light Transmission . 15. Since comlinks are limited to speed-of-light transmission range, they are of limited use for interstellar applications. 16. In the early 1970s, Thomas Soules pioneered computer modeling of light transmission through translucent ceramic alumina. 17. White-light transmission holography was invented by Stephen Benton. 18. Another age-related condition is cataracts, the term for the loss of light transmission through the lens. 19. By examining the star's ultraviolet light transmissions , astronomers can calculate back-and-forth shifts in the ultraviolet wavelengths. 20. ;Immunity to electromagnetic interference : Light transmission through optical fibers is unaffected by other electromagnetic radiation nearby.
