Answer:
Light from the sun travels through space in the form of electromagnetic radiation. Electromagnetic radiation is a type of energy that travels through the universe at the speed of light. It consists of oscillating electric and magnetic fields that move through space and can carry energy and information over long distances.
Light from the sun is produced by the process of nuclear fusion, which occurs in the sun's core. During nuclear fusion, hydrogen atoms are combined to form helium, releasing a tremendous amount of energy in the form of light and heat. This light and heat then travel through the sun's atmosphere and out into space, where it can reach the earth and other planets.
The light from the sun travels through the vacuum of space, which means that it does not need a medium (such as air or water) to travel through. It can pass through the emptiness of space and still carry energy and information. When the light from the sun reaches the earth, it is absorbed by the atmosphere and the surface of the earth, where it provides energy for various processes, including photosynthesis in plants and warming the earth's surface.
