Answer:
What did alexander graham bell invent during the industrial revolution
Step-by-step explanation:
Alexander Graham Bell is best known for inventing the telephone during the late 19th century, which is after the Industrial Revolution. However, he did contribute to various inventions and innovations during the Industrial Revolution period. In 1874, he developed a device called the "harmonic telegraph," which transmitted multiple telegraph messages simultaneously over a single wire. This invention was significant as it helped to improve communication efficiency in businesses and industries. Bell also developed a metal detector, which was used to locate a bullet in the body of U.S. President James A. Garfield after he was shot in 1881. Additionally, Bell worked on developing a hydrofoil boat, which was a type of watercraft that used submerged wings to lift the hull out of the water, reducing drag and increasing speed. However, this invention was not successful at the time due to technical limitations.
