A three dimensional view of an object requires three pairs of orthogonal directions. Orthogonal directions make right angles with each other. A point viewed on a three dimensional object can be described using three points.
Because we have two eyes, set apart, two different views of an object are sent to our brain.
You can test this by covering on eye, then the other, and seeing the picture shift.
This is parallax, your brain uses this information to add the third dimension - distance - to
the two "flat" pictures.
Its all in the eye. The part of the eye that lets us see things is the lens, and the retina. The retina has cones and rods, wich lets us see colors and dim light.

They are special.
easier for us to knowing different objects by their shapes, colours and textures
It isn't possible
Yes objects less than a mm apart can be seen as distinct objects. The lowest limit for the human eye to see is 0.1mm. If objects are any closer they are seen as being one item.
light
The visual system is what allows people to see things with.
Our eyes are specifically designed to detect light. The objects reflecting the light change the property of light, including its intensity and color; this allows us to make conclusions about the objects it was reflected from.Our eyes are specifically designed to detect light.

which form of electromagnetic energy allows us to see color
We see objects, because:* Light from the objects reaches us. * Our eyes (and brains) are especially equipped to detect such light.
nothing
The Sun's light, falling on other objects, allows people to see planets and other objects, which would be dark otherwise.
It allows us to see.
Cones
A lens bulges for close vision. Taking a close look at the eye in a mirror and one will see that the eye does indeed appear to be bulging forward slightly. This allows us to be ablow to see objects a little more closely when they're near us.
no
The Sun.
