Light is a type of energy that travels in invisible waves and always in straight lines. It has no volume or mass but we can see it. When an object blocks light, it forms a shadow. Light is actually made up of seven colors in the light spectrum, and every object absorbs some colors and reflects others, which is why a leaf appears green, a red car appears red, black objects absorb all colors and get hot, while white objects reflect all colors and stay cool.
