concept

When light falls on any object and the object reflects that light than only we are able to see the particular objects. As there is no particles in the space, light doesn't get reflected because of which space is seen black.

Take a comb and fix it on one side of a wooden block. Fix a mirror on the other side as shown in the figure. Spread a dark coloured sheet of paper between the mirror and the comb. Send a beam of light from a torch through the comb. You get a pattern of light similar to that shown in the figure. This activity explains the manner in which light travels and gets reflected from a mirror.
