Class 8 Physics Light No light No sight

No light, No sight

We see objects around us due to 2 factors (i) Eyes (ii) Light.

                                  

With eyes and no light, (as in night), we cannot see objects around us. Similarly, if there was light and an individual is visually impaired, he/she still cannot see. Therefore, we need both factors ie Eyes and Light to see objects around us.
