Answer :

On a calm day, when the surface of a lake is smooth and undisturbed, light rays reflecting off your image can easily reach your eyes without much distortion. This allows you to see a clear reflection of yourself in the lake.

However, on a windy day, the surface of the lake becomes rough and wavy due to the wind stirring up the water. This turbulence causes light rays reflecting off your image to scatter in different directions instead of bouncing back directly to your eyes. As a result, the reflection becomes distorted and unclear, making it difficult to see a sharp image of yourself in the lake.

In summary:
1. On a calm day, the smooth surface of the lake allows light rays to reflect back clearly, resulting in a clear image.
2. On a windy day, the turbulent surface scatters light rays, leading to a distorted and unclear reflection.
