A class of fourth and fifth grade students have emailed me some questions
about light. They are all good questions and a challenge to answer in the
vocabulary of this age group. However, one has me a bit stumped. Can anyone
point me in a good direction for answering the following?
Why does a road appear wet on a hot day?
We are having rainy weather here now, but I am assuming they are asking
about what we see at low angles from the road surface.
Thanks.
Richard
