We cannot see anything in a dark room because:
We cannot see anything in a dark room because:
- A. everything is black in colour
- B. our eyes do not work in darkness
- C. light from the room does not reach our eyes
- D. all the light gets scattered
Step-by-step solution
We see objects when light reflected from them enters our eyes. In a dark room, there is no light source, so no light reflects off objects and reaches our eyes. Option A is incorrect because objects have color but without light we cannot perceive it. Option B is false: our eyes work normally but there is no light to detect. Option D is wrong: scattering requires light to be present, but the room is dark.
