Question

As per the concept, we are able to see because the light gets reflected from the object and reach our eyes.but what when the light gets reflected but don't reach our eyes?

Answer 1

When light gets reflected and dont reach our eyes simply we cant see the object.

Actually thats why we cant see black hole actually.I guess you know what a black hole is. Black hole attracts every thing in the universe even it attracts the light and does not let any thing escape its attraction, so we cant even see the black hole because we cant see the reflected light.

In daily life be it the walls of the house or sky or trees or be it anything. We see it because the light gets reflected from it. Some portion of the light gets totally reflected and the intensity of light is high like when we see things in sunny surroundings. Similarly we see things in dark rooms with low intensity of light. Be you in a dark room or not, you see things because there is light reflecting, maybe be in higher intensity or lower intensity.

Hope this helps :)
