In speculation, if there never were rainbows until after the flood that doesn't necessitate that God would have had to change the properties of light. You still need rain followed by sunlight to get a rainbow and not every rainstorm produces a rainbow. If it rains and you don't see a rainbow, that doesn't mean the properties of light have changed, just that they (the properties) weren't observed (by a person) at that time.
Or it could be that there have always been rainbows but after the flood God gave the rainbow special significance. This leads into your last question.
"Sign of the covenant" is a remembrance. We see the sign, we remember the covenant.
If it could be proven beyond doubt that God exists...
and that He is the one spoken of in the Bible...
would you repent of your sins and place your faith in Jesus Christ?
