The SI unit of sound was named in honour of which physicist?

Correct option is C

The correct answer is (c) Heinrich Rudolf Hertz.
· The SI unit of frequency, which is related to sound, is named the hertz (Hz).
· Heinrich Rudolf Hertz was a German physicist who made significant contributions to the study of electromagnetism.
· He was the first to conclusively prove the existence of electromagnetic waves by generating them in his laboratory.
· The unit "hertz" measures the number of cycles per second, a fundamental concept in the study of waves, including sound waves.

· JC Maxwell: James Clerk Maxwell was a Scottish physicist known for his formulation of the theory of electromagnetism, but no SI unit is named after him.
· Werner Karl Heisenberg: A German theoretical physicist known for the uncertainty principle in quantum mechanics, but no SI unit is named after him.
· Albert Einstein: A German-born theoretical physicist best known for the theory of relativity, but no SI unit is named specifically after him.
