Question

what is a brownian motion and what is it used to verify​

Answer 1

Explanation:

Brownian motion may be considered a macroscopic (visible) picture of a particle influenced by many microscopic random effects. Brownian motion takes its name from the Scottish botanist Robert Brown, who observed pollen grains moving randomly in water. He described the motion in 1827 but was unable to explain it.

Larger particles can be moved by light, fast-moving molecules. Brownian motion is named after the botanist Robert Brown, who first observed this in 1827. He used a microscope to look at pollen grains moving randomly in water.
