ALL4’s: Is That Your Final Answer?

Last Month’s Answer and Winner:

There were four correct answers to last month’s Fourth of July themed question and Steve Smith of LyondellBasell was the first respondent who identified July 4^th, 1960 as the official day that our nation’s flag displayed a 50^th  star.   According to United States Code, the number of stars on a flag is updated on July 4^th following the date that a new state is admitted to the union.  Alaska was admitted on January 3^rd, 1959 and so there was, for a few months, a 49 star flag.  On August 21^st, 1959 Hawaii was added to the union with the 50^th star being added on July 4^th, 1960.  Congratulations to Steve and thanks for those who participated in the contest.

Question:

It is close to August vacation time and for me that means an annual trip to Niagara Falls.  Over the years, I have seen the Falls at least 100 times and it is an incredible site combining the awesomeness of nature with an amazing cross section of people from all corners of the globe.  One of the things that you can always count on seeing is a rainbow.  As the mist from the Falls rises, and with the sun to your back, a rainbow will usually be present.  If you look carefully there is more to the rainbow than just its colors.  For example, everyone has their own rainbow, as the rainbow is based on the geometry of you, the sun, and the mist.  Also, inside the rainbow the sky is slightly lighter than the sky outside the rainbow.  On a more rare occurrence you may see a second rainbow.  When this second rainbow appears, there is something unique about it.  Thus our July “Is That Your Final Answer” question asks “What is this unique characteristic about the secondary rainbow?”  Good luck!
