@paal.bjrndal: You have probably heard of lighthousekeepers that went mad. It was most likely because they had to handle mercury a lot. You have probably already guessed it had something to do with the fresnel lens, and you are correct. Here I tell you what it was used for and why it was only used at lighthouses with a rotating lens. #fyp #inspiration #learnontiktok #top #f
