The correct answer is Galileo Galilei – Wave theory of light

Key Points

  • Galileo Galilei is incorrectly paired with the wave theory of light.
  • Galileo Galilei was an Italian astronomer, physicist, and engineer, sometimes described as a polymath. He is known for his contributions to observational astronomy, including the telescopic confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter, and the observation and analysis of sunspots.
  • The wave theory of light is primarily attributed to Christiaan Huygens in the 17th century and was later expanded by other scientists, including Thomas Young and Augustin-Jean Fresnel.
  • Galileo's contributions were more focused on mechanics, motion, and astronomy rather than the wave theory of light.

Additional Information

  • Heinrich Rudolf Hertz is correctly credited with the generation of electromagnetic waves. He was the first to conclusively prove the existence of electromagnetic waves by generating them in his laboratory.
  • Albert Einstein is correctly known for explaining the photoelectric effect, for which he received the Nobel Prize in Physics in 1921.
  • Michael Faraday is accurately associated with the laws of electromagnetic induction, which describe how a magnetic field can interact with an electric circuit to produce an electromotive force (EMF).
  • The correct pairing for the wave theory of light would be Christiaan Huygens or Thomas Young.
