The progressive wave theory regarding of tides was put forth by

The correct answer is: D. G.B. Airy.

G.B. Airy was an English mathematician and physicist who is best known for his work on optics, astronomy, and tidal theory. He was the Astronomer Royal from 1835 to 1881, and he served as President of the Royal Society from 1871 to 1873.

Airy’s work on tidal theory was based on the assumption that the tides are caused by the gravitational pull of the Moon and the Sun. He developed a mathematical model that could predict the height and timing of the tides at any location on Earth. His work was a major advance in the understanding of tides, and it is
