"Visible" refers to something that can be seen or perceived by the eyes. This quality allows objects, colors, and shapes to be detected in the environment. For example, the sun is visible during the day, illuminating the sky and making it easier to see other objects around us. In science, visibility can be affected by various factors such as light, distance, and atmospheric conditions. For instance, fog can reduce visibility, making it difficult to see distant objects like cars or buildings. Understanding visibility is important in fields like navigation and photography.
