11. This causes fluctuations in the phase of polarized incident light . 12. Destructive interference eliminates the reflective wave, causing all incident light to enter the cell. 13. Experience taught me to play the game much cooler and to take incidents light -heartedly. 14. Incident light is focused onto a semi-transparent mask ( about 0.1 % transmission ).15. The appearance of reflecting objects is determined by the way the surface reflects incident light . 16. Energy conversion efficiency is measured by dividing the electrical output by the incident light power. 17. Reflectance is a physical property of a material that describes how it reflects incident light . 18. The equation for photoconductivity substitutes the parameters of the incident light for ? and is 19. Most scenes reflect just 12 % to 13 % of incident light falling upon them. 20. Thus, it is favorable to remove these low energy X-rays from the incident light beam.
