Answer:
The scientist who used a prism to study light was Isaac Newton.
Explanation:
Newton was the first to understand what the rainbow was: he refracted the white light with a prism and decomposed it into basic colors: red, orange, yellow, green, blue and violet.
For his experiments, Newton used triangular glass prisms. The light penetrates one of the faces of the prism and is refracted to decompose in different colors, because the degree of separation varies depending on the wavelength of each color. The prisms act in this way thanks to the fact that the light changes speed when it passes from the air to the crystal of the prism.
Once the colors were separated, Newton used a second prism to refract them and to form white light again. The experiment showed that the prism did not add color to light, as many believed. Newton also passed only the red color obtained with a prism for a second prism, thus discovering that the color was not altered. It was further proof that the prism did not create colors, but only separated those that were present in the original beam of light.
In large part it can be said that our current conception of light and color born with Isaac Newton and his valuable contribution to the subject.

Explanation:
The Cambrian Explosion refers to a epoch around 540 million years ago, when most of the major groups of animals first appear in the fossil record. It did not result in the evolution of dinosaurs, mammals, bacteria, or land animals, but the first representatives of most animal phyla.
The Cambrian Explosion is a term used to describe a period in Earth's history, about 540 million years ago, during the Cambrian period. This era signifies the time when most of the major groups of animals first appear in the fossil record. Therefore, the correct answer is that the Cambrian Explosion resulted in the evolution of the first representatives of most animal phyla.
It's worthwhile to note that the explosion did not result in the evolution of dinosaurs, mammals, bacteria, or land animals, these evolved much later. The Cambrian Explosion was unique because most of the multicellular organisms developed different body plans and organization than those of previous periods.
