1. Moonlight is spread out when it is reflected by the lake, since the surface is uneven.
2. Light is diffused when it reflects from an uneven surface. Here many parallel light rays from the moon are incident, but they are reflected at many different angles since the surface of the water has waves and not even. Hence, the image of the moon is not clear.
