What were Alexander Graham Bell's failures?

Answer 1

Alexander Graham Bell faced several failures throughout his career, particularly in his early experiments with sound transmission. Notably, he struggled with the commercial viability of his inventions, as he initially faced skepticism about the telephone's potential. Additionally, his attempts to develop a "photophone," which transmitted sound on a beam of light, were not successful in gaining widespread use. Despite these setbacks, Bell's perseverance ultimately led to groundbreaking advancements in communication technology.
