Which observation can best be explained by the scattering of light? a) a pencil appears bent when placed in water. b) an oil drop displays seven different colors. c) a light beam’s path becomes visible in mist. d) an image is formed on the surface of still water.

The correct answer is "A light beam’s path becomes visible in mist".

Explanation:

Scattering: It is the phenomenon in which there is change in the direction of the motion of the particle due to the collision of particle with the another particle.

The molecules and particles are found in the atmosphere. These particles in the atmosphere have the ability to scatter radiation in all direction.The particles or molecules are the scattered particles for the light.

From the given options, the best observation can be explained by the scattering of light is "A light beam’s path becomes visible in mist".Here, the particles of the mist scatter the light and these particles make the path visible for the light.

Therefore, the correct option is (C).
