The Highway Isn't Wet -- It's Light Refraction!
« on: February 08, 2020, 07:07:30 PM »
Anyone else notice those mirages where something looks wet when it really isn't?  I usually see it when on the highway on a hot day.  I've always wondered what causes it.  After many years, now that I'm going into the field, I decided to look it up.  I'm posting this for anyone else to see in case they have ever wondered, too.

It's really refracted light, and the "puddle" you're seeing is really a reflection (refraction?) of the sky!

I've wondered that!  This happened a lot to me when I was driving through the desert highways in Arizona and Nevada.  It's pretty crazy how hot it gets on the road in the summer months.  People end up at the hospital for burns from the pavement or asphalt!
