Answer 1

Answer:

Brownian motion.

Explanation:

Brownian Motion is the path which is traced by such single particles. It is the randomness of the smoke particles of the incense stick or any particles suspended in the fluid resulted from the fast moving particles in the medium causing collision.

The theory of the Brownian motion is proposed by Albert Einstein. Since, the particles emitted from the incense stick is having some force of attraction between them hence the y follow Brownian movement or the zig-zac pattern of motion.
