Choose the correct statements:
Statement 1: We see objects when light emitted from the objects enter our eyes.
Statement 2: We see objects when light reflected from the objects enter our eyes.
Statement 3: Eyes alone cannot see an object.
Statement 4: Eyes emit light rays in all direction.
Statements 1, 2 and 3 are correct
We can see an object when the light from an object enters our eyes. We see non-luminous objects (objects which do not emit light of their own) because the objects reflect the light from another source into our eyes.
