A sunbeam is a ray of light that comes from the Sun. It is a visible part of sunlight that travels through the atmosphere and can illuminate spaces on Earth. Sunbeams are often seen during clear days when the sun is shining brightly, creating patterns of light and shadow. Sunbeams can also have various effects on the environment. They provide warmth and energy, which are essential for photosynthesis in plants. Additionally, sunbeams can create beautiful visual effects, such as rainbows or sunsets, when they interact with water droplets or atmospheric particles.
