Interference of the eleventh- and higher-order rainbows formed by a pendant water drop

摘要

Interference of the 11th- and higher-order rainbows formed by a pendant water drop was studied by use of laser beams of wavelengths 632.8 and 532 nm. Time variations of the corresponding glare-point intensity, due to vibration of the droplet, are in agreement with results of a simple model calculation. Our results are compared with the "non-Debye enhancement" of the 11th-order rainbow reported by Lock and Woodruff. (C) 2003 Optical Society of America. [References: 14]
