Because the particles in the sample are moving due to Brownian motion, the intensity of light varies with time yielding a noisy signal. Smaller particles diffuse more rapidly than larger particles, which means that fluctuations in intensity with a small particle occurs more rapidly than for a large particle, as seen in Figure (PageIndex{3}).
