Yes, it can do.
Yes. Science is the study of how and why things do as they do. Optical Illusions are ways to trick your brain into perceiving something in a way that its not. Knowing how and why Optical Illusions do that is all science.
Rainbows are an optical illusion, they are not "real". You cannot view them from above; they will always appear the way they appear from the ground.
Illusory motion is also know as motion illusion. Illusory motion is an optical illusion in which a static image appears to be moving due to cognitive effects of interacting color contrasts and shape position.
Not necessarily, it depends on how different you perceive a shape/object from its original version. If you tend to see something quite different then you could have symptoms of optical illusion. As far as color goes, most people have some percentage of color blindness and that doesn't necessarily relate to this illness. You could perhaps be considered color blind if you tend to lack difference in perception about some/all colors.
why is all planet are in circle shape? the planet earthis actually slightly pear shaped, its an optical illusion of sorts that makes them all appear spherical. An oblate spheroid
Well, no. Although optical illusions can distort your vision somewhat, they cannot permanently damage your eyes. If you have had eye problems in the past, though, you may want to be wary of optical illusions. ~
Thw moon doesn't change shape. It is an optical illusion caused by the moon's orbit around us and the way sunlight hits it. Since we can't see the "dark side" of the moon or the "far side" of the moon when it is full, it looks like the moon is changing shape.
If a solid body has a 3 dimensional shape, without illusion; It could be touched and do not change its shape time to time, then we can be sure that the body has a particular shape
A surface on a multiview drawing that does not give a clear or accurate representation of size or shape and should not be dimensioned.
The shape of an object bears no relation to the mass of an object.
Every object, device, or anything else, require a determined shape in order to be functional or attractive.
This has nothing to do with shape. The apparent magnitude means how bright a star looks to us. The absolute magnitude means how bright the star really is (expressed as: how bright would it look at a standard distance).
