The object must be opaque, solid or liquid.
When light falls on some object, then it absorbs all the colors of visible light spectrum except the color of the object itself which it reflects back (diffusion). So we see the color of the object .
A hot object must be directly touching a cold object.
it must be smooth
An object must have mass and take up space.
No you see the object because the light refelects from the object into your eyes
-- You "see" only when light enters your eye. -- You 'see' an object only when light from that object enters your eye. -- If the object itself doesn't generate light, then light from some other source must illuminate the object, and some of that light must reflect from the object to your eye. -- In absolute darkness, there is no light, and you do not 'see'.
you have to look around the area were the object mite have been at
A stationary frame of reference.
Designers must know the volume and surface area of an object because they must know how much space the object has inside it to put mabey parts in the object and to see how much the object weighs to see if it can fit somewhere without breaking it
1. there mush be a source of light 2.the light must strike an object 3.the light must be reflected from the object to your eye
because light used to see an object must have a wavelength
You will be unable to see, or unclearly see, the object in which you are viewing.
how do we see things?...There must be a light source that strikes or shines on the object and reflects and to reach your eyes..,
The fact that we see things is based on LIGHT. Light from an object must come to our eyes - whether the object emits light itself, or reflects it from some other light source.
