Unseen Passage for Class 3 - Passage 13
Posted by Olympiad Tester on
Unseen passage - Alexander Graham Bell, a teacher for the hearing-impaired in Boston, is credited with the invention of the telephone. While working on experiments with a telegraph at night, an accidental discovery led to the development of this groundbreaking device. During one experiment, when the metal in the telegraph got stuck, Bell's assistant, in an attempt to loosen it, inadvertently created a sound. Although Bell was in a different room, he heard the sound in his receiver and realized that the vibrations had traveled through the electric current to the receiver. This discovery sparked his interest, and he continued to explore and refine the concept.
On March 10, 1876, Bell achieved a significant milestone by successfully speaking words over a telephone line for the first time. While testing a new transmitter, an unexpected mishap occurred as he spilled battery acid on his clothes. In response, Bell urgently called out to his assistant, Mr. Watson, who was in another room, using the famous words, "Mr. Watson, come here! I want you!" Astonishingly, Watson heard every word clearly on the telephone and promptly rushed into the room.
Eager to share his invention, Bell demonstrated it to numerous individuals. With time, an increasing number of telephone lines were installed, making this groundbreaking invention accessible for use in homes and businesses.
