The correct answer is: A. James Clerk Maxwell.
James Clerk Maxwell was a Scottish physicist and mathematician who is best known for his work on electromagnetism. He developed the theory of electromagnetism, which is the basis for all modern electrical and electronic technology. Maxwell also discovered the relationship between electricity and magnetism, and he predicted the existence of electromagnetic waves.
Heinrich Hertz was a German physicist who is best known for his experiments on electromagnetic waves. He was the first person to produce and detect electromagnetic waves, and he proved that Maxwell’s theory of electromagnetism was correct.
Thomas Alva Edison was an American inventor and businessman who is best known for his invention of the light bulb. He also invented the phonograph, the motion picture camera, and the alkaline battery.
John Logie Baird was a Scottish engineer and inventor who is best known for his invention of the television. He was the first person to transmit and receive moving images over radio waves.
Maxwell’s work on electromagnetism was the foundation for all of the later work on electromagnetic waves. Hertz’s experiments proved that Maxwell’s theory was correct, and Edison and Baird’s inventions made use of electromagnetic waves. However, it was Maxwell who first developed the theory of electromagnetism and predicted the existence of electromagnetic waves. Therefore, he is the scientist who first sent electromagnetic waves to distant places.
