Hi all
Tearing my hair out trying to calculate the Maximum acceptance angle for a problem. Experiment involved shining a laser into a tube of water. I have calculated the angle of refraction based on the average of two critical angles (one known and one measured manually) as 52.49 degrees. Asked to calculate the maximum angle of acceptance with just the critical and the angle of refraction. I am of the opinion that more information is needed, can someone please clarify.
Ive tried several geometric ways around this and can't get it?
Cheers
