Answer:
Light is electromagnetic radiation that travels through space at a very high speed. When light enters our eyes, it interacts with the cells in the retina at the back of the eye, which convert the light energy into electrical signals. These signals are then sent to the brain, which processes them to create the sensation of vision.
So, in order to see an object, light must be emitted or reflected from that object and enter our eyes. Without light, we cannot see anything. Additionally, the characteristics of light, such as its intensity, color, and direction, affect how we perceive the object.
