11. Therefore, the achievable electromagnetic and optical effects can be extended. 12. The polymerics align in microdomains facing all different directions, which ruins the optical effect . 13. In radio, this approximation is used to estimate some effects that resemble optical effects . 14. Yamamoto is primarily known for his work in the 1980s on quantum optical effects . 15. They predict optical effects will be the next change _ metallics, opalescence and iridescence. 16. This phyllotactic pattern creates an optical effect of criss-crossing spirals. 17. Switching is obtained using nonlinear optical effects when two or more signals are combined. 18. The time of day and weather change the optical effects . 19. And with optical effects these days, that's done quite easily. 20. The optical effect in the spherical mirror produced real images resembling that of a hologram.
