When an object moves at speeds that are close to that of light its length will?

Not change, from the frame of reference of the object, that being more or less the whole point of special relativity.
From the point of view of an outside observer, it will contract along the direction of motion.

Does eyesight have speed?
Yes. Light has a speed, electric impulses from the retina to the brain have speeds and the neurons in the brain have speeds.
How does visible light interact with an object?
The Answer is color. Because color has to do with light and physical properties.
Does convection or conduction travel at the speed of light?
No. The speeds of convection and conduction vary, but they are nowhere near the speed of light.
When light falls on an object which side do shadows fall?
The shadow will fall on the opposite side that the light hit the object. Assuming that the object is a solid object that you cannot see through, there would be no light on the other side, hence causing the shadow.
Do types of electromagnetic waves differ in their speeds?
No. As long as radio, light, and X-rays are all traveling through the same stuff, their speeds are the same.
Is length a constant?
No, length is a relative measure. If an object is travelling close to the speed of light it undergoes Lorenz contraction.
What does an object do to light so you can see it?
Reflects all light beams which have the wave length of the color of that object. Each color has a particular wave length in the electromagnetic spectrum.
What is the relationship between the size of the shadow and the distance of the object from the light source?
The relationship between the size of a shadow of an object and the distance of light source from the object is indirectly proportional. A short distance will make the shadow big while making the distance long will reduce the size of the shadow.
How can we know that people traveling at or close to the speed of light will not age as fast as someone not traveling at such speeds when we have no means of reaching such speeds?
Einsteins theory of relativity
What has mass volume and density but not length?
An object moving at the speed of light.
What is a practical example of gravity acting on a moving object?
A car speeds up as a traffic light turns green.
Object traveling through the speed of light?
Electrons are able to travel close to speed of light.
How does the length of a shadow get longer?
The light source moves strait above the object
When a light is close to n object the shadow formed is big because?
The angle of the light passed the edge of the object is greater, creating a larger shadow.
what causes shadow length?
The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.
Why does a flashlight shine brighter on objects to which it is closer?
The close object reflects light to eyes when a flashlight shines on the object.
How does the focal length of eye changes from a near object to far object?
When you're looking at a near object, the light rays converge at a point behind the retina so the focal length of your eye increases so that the parallel rays of light converge on the back of the retina. Therefore, if you're looking from a near object to a far object, the focal length of your eye should decrease back to its normal, relaxed size.
