I've been reading the list for a while. This is my first post.
I'm having trouble finding an accurate image (ray diagram) of white
light dispersed by an equilateral triangular glass prism. All the images
I can find seem to show much more dispersion than is the case. Has
anyone else had this experience? Does anyone know where I can find an
accurate image?
I know I could draw one myself, but it would also be nice to see one
ready-made.
