A few sample questions
1. The Lighthouse of Alexandria (Pharos), one of the Seven Wonders of the Ancient World, was located in which country?
Answer: Egypt
The Lighthouse of Alexandria was built on the island of Pharos in Alexandria, Egypt, around 280 BC. Standing approximately 100-130 meters tall, it was one of the tallest structures in the ancient world and guided sailors for centuries.
2. What revolutionary lens system, invented in 1822, dramatically improved the brightness and range of lighthouse beams?
Answer: Fresnel lens
The Fresnel lens, invented by French physicist Augustin-Jean Fresnel in 1822, uses concentric rings of prisms to concentrate light into a powerful beam. It could make a lighthouse visible from over 20 miles away.
3. The Eddystone Lighthouse, located off the coast of Plymouth, England, was notable for being built on what?
Answer: A dangerous reef in the open sea
The Eddystone Lighthouse was built on the treacherous Eddystone Rocks, a reef 14 miles south of Plymouth. It has been rebuilt four times since 1698, with each version overcoming the extreme challenges of building on exposed rock in the open sea.
