from a purely mathematical stand point, if something were to reach the speed of light the time dialation/length contraction formula would yield something over 0. This is beacuse the formula is:
constant/[(1-(velocity/speed of light)^2]
as you can see, if velocity=speed of light, you get something over zero.
Depends on the surface of the object that the light is projected on. If the object has a polished surface like an inoxidable steel, or the object is a mirror, the light will produce a reflexion or the light comes back when it hits the mirror. Behind any object, is formed a shadow, since such object is not a glass.
an opaque one
Opaque objects don't allow light to pass through them while translucent objects slow the passage of light but ultimately allow it to pass through.
Henrik Antoon Lorentz has written: 'Sichtbare und unsichtbare Bewegungen' -- subject(s): Motion, Light, Electrons, Kinetic theory of gases
light from the sun bounces back from objects but eyes only allow light which has bounced back from an object.
It is due to Einstein's theory of special relativity. If an observer views an object that is moving relative to him then it undergoes a length contraction. This is known as the Lorentz contraction. The contraction is by a factor of sqrt(1 - v2/c2) where v is the relative velocity between the observer and the object and c is the velocity of light.
Transparent objects allow the complete passage of light. No light goes through an opaque object. Between these two extremes, objects are said to be translucent.
To answer why delves into philosophy or theology. Why is there gravity - there just is..The relativistic mass is the mass an object possesses because it travels at speeds that approach the speed of light ('c'). According to the Lorentz factor, the relativistic mass of an object increases as an object's speed approaches c as follows:.mrel = m / (1 - v2/c2)1/2.where:mrel is the relativistic massm is the rest massv is the object's velocityc is the speed of lightRelativistic mass is only significantly greater than rest mass for objects travelling faster than 0.1c, or one tenth the speed of light, or about 108,000,000 KPH (67,000,000 MPH). As you can see from the above equation, the denominator approaches zero as the object's velocity approaches the speed of light, making the relativistic mass unbounded..The Lorentz factor also applies to an object's momentum and its energy. This means not only the mass, but also an object's momentum and energy approach infinity as the object's speed approaches c. Note that, in this context, an object's rest energy is in according to the equation:.E = mc2.and this energy increases as the object's speed approaches c.
same way normal light does. it's just normal light bouncing off a reflective surface and onto another surface
Allowing for rounding I would make a wild guess and say exactly 8 feet. Unless the object had a velocity close to the speed of light relative to the observer and Lorentz contraction took effect, as required by Einstein's Relativity Theory.
No, that is what opaque means. Light does not go through an opaque object. An object that is translucent will allow light through, but is opaque enough to keep you from seeing clearly through it (think about frosted glass used for bathroom windows). Transparent is "see through".
transparent Transparent allows light images to pass through. Translucent object allow light through but no image. Th opposite of light transmission would be objects that are opaque.
