According to

"Robert Hooke (1635-1703) who started as an assistant to Robert Boyle, published in 1667 an explanation of light as waves. White, natural light according to Hooke is a simple uniform pulse at right angles to the direction of propagation. Blue light is a confused pulse whose weakest part precedes and whose strongest follows. Red light is a confused pulse whose strongest part precedes the weakest part. Refraction changed the light's color."

This theory was not correct, since the perceived color depends upon the frequency of the waves, not the shape of individual wave "pulses". Yet he was on the right track by proposing a wave theory, with the oscillation perpendicular to the direction of propagation.

What is the contribution/s of Robert Hooke in Cell Theory?
