摘要
High-order rainbows, up to the 200th order, formed by a pendant water drop and a 50-mW laser beam, have been observed. Some of the characteristics of the high-order rainbows, including angular intensity distributions and angular positions, are reported. Rainbow intensity as a function of order number is also presented. Rainbows beyond the 32nd order have been observed for the first time to our knowledge. Experimental and theoretical results are in reasonable agreement. (C) 1998 Optical Society of America [S0740-3224(98)00411-1].
