Menlo Park and Edison’s Research
What was the focus of Edison’s research at Menlo Park?
Edison focused on finding the right materials and methods to make a practical, lasting light bulb.
Why was a vacuum necessary inside the light bulb?
The vacuum prevented the filament from burning up quickly by reducing the amount of oxygen inside the bulb.
What material did Edison use for the filament in his light bulbs?
Edison used carbonized bamboo for the filament.
Who were some of the key scientists in Edison’s team?
Some key scientists included engineers and researchers at Menlo Park.
How did the light bulb change daily life in the late 1800s?
The light bulb extended the day, allowed for safer lighting, and contributed to the growth of industries and urbanization.
How did Menlo Park contribute to the success of the light bulb?
Menlo Park was where Edison and his team refined the light bulb design, making it practical and affordable for mass production.
How did Edison improve the vacuum inside light bulbs?
Edison improved the vacuum by reducing the amount of gas inside and creating a better seal around the bulb.
What was a key material used in Warren de la Rue's early light bulb design?
Warren de la Rue used platinum for the filament in his design.
