Traveling at speed of light how much time will pass in 70 years on earth?
None. At the speed of light, time stops completely. It is impossible for anything with an invariant mass to move at the speed of light; only particles with no "rest mass" (such as photons) can do so.
If a solid mass travels at the speed of light and it passes through the suns ray to earth would it be seen?
A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.
Relationship of the speed of light in a vacuum to the speed of light in a medium where it will pass through?
Refractive index is the ratio of speeds.
What are the effects of traveling at near the speed of light?
If you travel near the speed of light, then, from the point of view of somebody who is NOT travelling with you (say, someone who stays behind on Earth):Time will pass slower for you.Distances for you will be shorter (in the direction of travel).Your mass will increase.
Can you pass the speed of light?
In all but very exceptional circumstances, no.
If two entities are traveling to each other with 60 percent of the light speed is one going back in time from the viewpoint of the other?
No, time will appear to pass slower, but that doesn't mean time will seem to go backwards.If EACH object travels at 60% of the speed of light with respect to Earth for example, then their relative velocity will still be less than the speed of light. The traditional formula for simply adding up velocities doesn't work in this case.No, time will appear to pass slower, but that doesn't mean time will seem to go backwards.If EACH object travels at 60% of the speed of light with respect to Earth for example, then their relative velocity will still be less than the speed of light.

When a ray of light passes from water to air speed increases?
Yes. The speed of light in water is approximately 2/3 the speed of light in air.
If you were to set up a ship travelling at 80 percent the speed of light if you stayed on the ship for 1 year how many years would pass on earth?
Time slows down by a factor of 1 / square root of 1- (v2 / c2), where v is the velocity (or speed) of the object, and c is the speed of light.
If you leave Earth traveling at the speed of light in a circular pattern and your twin stays on Earth observing you when you eventually reach your twin who will be older?
According to the theory of relativity, time dilation occurs as an object's velocity approaches the speed of light. As a result, time will appear to pass slower for you as you travel near the speed of light compared to your twin who remains on Earth. Therefore, when you eventually reach your twin, they would be older than you.
Can you feel time elapsing if you travel at the speed of light?
Of course. You feel completely normal no matter what speed you happen tobe traveling. If you pass other people and they measure you as you pass by,they're the ones who notice weird things. If you pass them at the speed of lightwhile they measure you, they find that your mass is infinite, your front-to-backthickness is zero, and your heart and your wristwatch have stopped.What's even morre weird than that ... if you measure the other people whileyou pass them, you find exactly the same things about them, althougheverybody feels completely normal.And, by the way, if they shine a flashlight at you as you pass, and you shine aflashlight at them, their light passes you at the speed of light, and your lightpasses them at the speed of light.
What property of light waves can be observed as light waves pass from one medium to another and change speed?
diffraction
Which is the minimum speed of light passes through?
Zero (0) light cannot pass through opaque materials.
