What happens to the colored water?

Hannah P asked:


What happens to the colored water? How does this show what happens to pollutants that are left behind when water evaporates?

How a spectrum is displayed on the wall when using a pocket mirror and water?

nicki11 asked:


Ok, so I am doing an experiment for class and found the results but don’t know how to explain them. I placed a small tray of water in a windowsill containing bright sunlight. Using a pocket mirror, I leaned it towards the window and a spectrum (basically a rainbow) was shown on the wall. So how exactly does this work? The light does what? to make the rainbow colors on the wall.

I’m sure it has to do with refraction, but am at a loss for explaining it. Thanks for any help. :)
