I am doing a special photo-book project inspired by Richard Dawkins' Unweaving the rainbow and other peices. I have about 15 images in mind so far - basically it will be a combination of photo-art and short explanations of what it is representing/what is happening, etc... kind of like APOD. I will spare the details as it is a Seeeekrit project for now.
I am however, having some troubles finding certain things we will need for the photo shoot. Some I am sure can be found on google, but I also have questions about them so I included them here:
A Prism: Probably can buy anywhere online. But how do you, or can you, adjust the spread of the colors? So you can have the entire rainbow being a rough specific width?
Wave-machine: We had one of these in high school: basically you took your old school high school overhead projector, put a dish of water on it, and put this thing in it and it would make waves. You can adjust the speed. Then you put various blocks in front of the waves to make different patterns and see how they interact.
Double slot experiment: We can probably make do with a strong light and a peice of card, or does it have to be a specific light? My friend is a professional photographer so has access to some lights.
Eclipses: We want to simulate an eclipse, to get a picture of that cool effect (like this:
http://www.petapixel.com/assets/uploads ... _mini1.jpg). Is there a simple way to do this? Perhaps with a circular light and an occultation disk with a screen in front of it to break it up into the multiple shadows?
As well, I am open to other sorts of ideas for what we can photograph - we're also doing pictures involving refraction, a sun-glory, relativity, and other things. I'd love to include other sciences other than light in this project book! They will involve photos of a model in each one though, so keep that in mind. we were thinking of having models pose in front of various constellations, but there arent that many that are human.
Feel free to run wild with suggestions!
