Question

We would not be able to see any object around us if light does not get reflected how do you appreciate the property of light

Answer 1

Simply saying, we can't see light. We are seeing the object which is producing light. Light is made up of subatomic particles called photons. Even if we travel at speed of light, we can't see light moving with us as speed of light is constant. Do you mean red light? Red light is light with lowest frequency. The stars which are about to die that are so-called red giants produce red light. This is because they have to loose minimum energy.(E=hf). You can never see light.
