Lighthouses Are Not Just a Chandelier

Lenses were created by a gy called augustin jean frenel, who realized that light is a transverse wave. The lenses would have been incredibly heavy if you'd just made a single lens. So he created this clever lens, which can be much thinner, but it has dozens of prisms,. and they all focus the light. But the reall equal thing about those heavy, great lenses at the top is they were created to float ateo mercury. And so the whole lighthouse top was just floating on. This is quite dangerous. Ye, don't call it a bath if you're in that house with ki ha.
