Cancave mirrors are used in car head lights Why?

The light rays come together to make a bright spot of light. When a concave mirror is used in car headlights, a bulb is placed at the spot where light would come together. This has the effect of making the opposite happen. The rays of light shining out from the bulb are reflected off the concave mirror to make a strong beam of light, which travels out in front of the car to shine on the road.


If you were travelling at the speed of light and turned on a torch in your spaceship would you see a beam of light from the torch?

You can't travel at the speed of light. Accelerating a finite mass to lightspeed requires an infinite amount of energy.If you were traveling at nearly the speed of light, relativity says the beam of light from the torch would appear to you to be traveling just as fast as it would if you were standing still.Uh, it's a bit academic, but in reality there's nothing that says a mass can't travel faster than light. While it's true that a mass can't be accelerated to the speed of light from any lesser velocity, it doesn't rule out masses that might always have had a velocity greater than the speed of light.
