Why do black shiny surfaces reflect all colours of light?
This is a question that came up from a discussion with a colleague yesterday. I have recorded a quick video, but I need to add more to it and edit it. Here’s a behind-the-scenes, unedited upload of the video (an exclusive for those weekly subscribers!). Just log in below and see the work-in-progress.
Don’t forget, this week’s session is tonight, not Thursday!
