Since the object appears violet to your eye, it must be that violet light is the wavelength most efficiently reflected ... least efficiently absorbed ... by the object. To a greater or lesser degree, all wavelengths that are not reflected from the object are absorbed by it.
The compound microscope enables us to see microscopic objects more clearly than the naked eye or the simple microscope
The background color of a photograph would rely a lot upon personal taste, the environment the picture is being taken, and several other factors. In general, it is good to have a black background, so the objects in the front can be seen more clearly and be the focal point of the photograph.
The question is a little off. Sunlight isn't 'attracted' to anything, in the sense that light 'wants to move toward' certain colors. But when light shines on objects of different colors, different parts of the light are reflected off of the objects and absorbed by the objects. An object that is close to a very pure white color will reflect most of the light that shines on it; an object that is close to a very pure black color will absorb most of the light that shines on it, and so will absorb more energy.
because the iris allows you to see in dim light
Nearsighted people can see objects that are close more clearly than objects that are far away.
Emmetropia is when light is focused exactly on the retina and vision is perfect. Farsightedness is called hyperopia. This condition occurs when the eyeball is smaller than normal and light rays from near objects do not focus properly on the retina at the back of the eye. A person with hyperopia can see distant objects more clearly than closer objects.

binoculars, glasses, telescope
They have a lower "albedo" if you will. Light objects reflect light at a greater rate than dark objects which absorb it. This is why dark objects heat up more than light ones.
When the object under observation is well lit, then you can view it more clearly. Some objects which you want to observe under magnifying glass, may not have been well lit naturally. Magnifying glass with lights will help look at it more clearly.
This is because the dust particles are removed after rain
More collecting area means that more light is collected. This allows seeing fainter objects - objects that emit less light, from which we receive less light per unit area.
The ability to make images bigger is called refraction which bends light. Magnifying glasses help make objects bigger so they use refraction.
Because dark colours absorbs light, and energy;and its named absortion coefficient. ============================== Some substances and objects made from them reflect more light and absorb less. Other substances and objects made from them reflect less light and absorb more. The ones that reflect more and absorb less are the ones that appear lighter to us. Why ? Because they absorb less light and reflect more of it toward our eyes.
