Quiz Answer Key and Fun Facts

1. The magnification of the light is caused by the lens or optics.

Answer: True

Optics are built from complex arrangements of lenses and prisms.

2. Caisson is the method of construction whereby a screw on the end of each leg of the lighthouse is screwed into the sea bed.

Answer: False

It's called Screw Pile. Today, four of three screw-pile lighthouses survive, all in the Chesapeake. They are Thomas Point, Drum Point which now rests at the Calvert Maritime Museum, Hooper Strait at the Chesapeake Bay Maritime Museum, and Seven Foot Knoll, recently moved to Baltimore.

3. What is the most common material used to build lighthouses?

Answer: Brick

By 1859 nine brick towers over 160 feet had been built and six more were constructed after the Civil War.

4. The first lighthouse to use electricity was the Statue of Liberty.

Answer: True

As one of the most recognizable monuments in the world, the Statue of Liberty is often not thought of as a lighthouse. The statue was designed with glass inserts in the sides of the torch held high by Lady Liberty which would serve not only as a symbol of freedom but as a light to help ships safely navigate into the harbor.

8. What is the name of the room where the optic is located?

Answer: The lantern room

It is often made of iron and has a double-door system to make sure the inside of the room wasn't directly exposed to the outdoors. The separation of the interior of the lens room from the outside environment helps to keep the interior as clean as possible and protect the room from sudden changes in temperature.

Pressed from wild cabbages, it replaced whale oil in the early 1850s.
