Who started with "FIbre Optic " defined term and also is considered a Pioneer in the field.*Charles KaoNarinder KapanyJohn Tyndall

Narinder Singh Kapany is often referred to as the "father of fiber optics" for his pioneering work in the field. He coined the term "fiber optics" in an article in Scientific American in 1960, and his research laid the groundwork for the development of optical fiber technology.

Charles Kao is also a key figure in the history of fiber optics. He shared the 2009 Nobel Prize in Physics for his work in the transmission of light in fibers for optical communication.

John Tyndall is known for his demonstration of the principle of total internal reflection, which is the fundamental principle that makes fiber optics possible. However, his work was in the 19th century, long before the term "fiber optics" was coined and the technology was developed.

Narinder Singh Kapany is often considered the "father of fiber optics." He coined the term "fiber optics," published a key article in Scientific American in 1960, and wrote the first book about the new field. His research and inventions have laid the groundwork for the development of the internet, cable television, and many medical devices. Charles Kao is also a significant figure in the field of fiber optics, having been awarded the 2009 Nobel Prize in Physics for his groundbreaking achievements concerning the transmission of light in fibers for optical communication. John Tyndall is also a key figure in the history of fiber optics, having demonstrated that light can be conducted through a curved stream of water, proving
