You see objects because visible light( a small portion of the electromagnetic spectrum) is reflected off the surface of something into your eye. All different colors have a different wavelength which defines their frequency. When you see a red object, that object is absorbing all the colors except for red which is then reflected into your eye.
No, color can not be seen in the dark. The only color that can be seen in the dark is black, because it is dark. If it is not completely dark then you might be able to see the color of some objects.
We can see non-luminous objects because the light reflect off the object and into our eyes that's why at night you can only see a faint out line of the objects around you
...objects are perceived to be the same color even if the light they reflect changes.
Opaque objects do not allow light to pass through them, so they block the path of light. This means that we are not able to see through them. Instead, we see these objects by the light that bounces off their surfaces and enters our eyes, which allows us to perceive their shape, color, and texture.
No, periscopes allow you to observe objects while you are hidden.
you see coloured objects by the light. light makes the color of the object
The color is reflected by the light to your eyes. That is why you see color.
It appears the color of light it reflects.
because whatever color you see is the color the object reflects in light.
You can see objects because your retina is sensitive to light and you eyeball can focus it. You can't "see" color - that's a frequency coding illusion that your brain makes up for you.
Yes, you can see a color when light of a certain wavelength reaches your eye.
