​Rahul decided to take a walk through a forest early in the morning. While he was inside the dense forest, he could see the beautiful sunrays through the small gaps within trees and clearly see the path taken by those rays. Of which effect was this a result?​

Correct option is D

• ​The Tyndall effect occurs when light is scattered by particles in a colloid or suspension.
• In this case, the sunlight passes through the gaps in the trees and encounters tiny particles in the air, such as dust, pollen, or water vapor.
• These particles scatter the light, making the paths of the sunbeams visible.

Incorrect options explanation:

• ​Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.
• Diffraction is the spreading out of waves as they pass through an aperture or around objects. It occurs when the size of the aperture or obstacle is of the same order of magnitude as the wavelength of the incident wave. For very small aperture sizes, the vast majority of the wave is blocked.
• Dispersion refers to the range of potential outcomes of investments based on historical volatility or returns. Dispersion can be measured using alpha and beta, which calculate risk-adjusted returns and returns relative to a benchmark index, respectively.
