Light as Energy

Light is a form of energy that travels in waves and particles called photons. It carries energy from the sun or other sources, allowing us to see and providing power for processes like photosynthesis in plants. Unlike other forms of energy, light can move through empty space without needing a medium, which is why sunlight reaches Earth through the vacuum of space. This energy can be converted into other forms, such as electrical energy in solar panels, or used in technologies like lasers. Overall, light is a fundamental energy that enables vision, influences climate, and powers numerous natural and technological systems.
