What are the properties of light Class 8?

(i) Light is a form of energy, which includes the sensation of vision in our eyes and make us able to see various things present in our surrounding. (ii) When light falls on an object, some part of light is reflected back to our eyes. Then, we are able to see an object because of light being reflected from the object.
