Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Thomas Edison's first patent was US Patent 90,646 for the electric vote recorder, filed in 1869 when he was 22 years old. This device allowed legislators to vote yes or no by turning a switch, which would record votes electronically. Unfortunately, it was not commercially successful because politicians were unwilling to speed up voting processes. Edison vowed to only invent things people would actually buy after this failure.

  2. False

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is false. In 1877, Edison invented the first phonograph prototype, but he used wax paper wrapped around the grooved cylinder, not tin foil. The tin foil version came slightly later as an improvement. The wax paper version could record and play back sound, but the quality was poor. Edison continued refining the design, eventually using tin foil and later wax cylinders for better sound reproduction.

  4. x-ray

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Edison's fluoroscope was an early X-ray imaging device that used fluorescent screens to make X-ray images visible in real-time. This technology became commonly known as X-ray imaging or simply 'X-rays' in medical practice. Edison himself stopped working on X-ray technology after his assistant Clarence Dally suffered severe radiation damage and died from X-ray exposure, highlighting the dangers of early radiography.

Multiple choice general knowledge
  1. Menlo Park

  2. West Orange

  3. South Orange

  4. East Orange

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Thomas Edison developed the first motion picture film (movie) at his laboratory in West Orange, New Jersey in 1889. This was a significant breakthrough in cinema history, building on his earlier work with the phonograph. West Orange became Edison's primary research facility where he developed many of his most famous inventions, including improvements to the motion picture camera and projector. Menlo Park was his earlier laboratory site.
