max.yevs Posted March 25, 2009 Posted March 25, 2009 (edited) given the amount of speed of light questions here, this may have been answered already, in that case i apologize in advance. light moves at a speed of 670,616,629 mph... now, say you are driving a car at 50 mph, and you turn your headlights on- will light be moving at 670,616,679 mph? or would it still be moving at 670,616,629? or is it like soundwaves that it will become compressed and turn into a higher frequency? so if you're going faster than the speed of light, would you be shining behind you? and if you're going exactly the speed of light, would your headlights blow up from illuminating all their light onto themselves? i'm sorry, almost the same exact post is 15 posts below... if admin knows how to remove this thread, please do Edited March 25, 2009 by max.yevs
samtheflash82 Posted March 26, 2009 Posted March 26, 2009 the speed of light is constant. it is always travelling at more or less 670,626,629 mph. the light from your car headlights will not be going any faster than the light from the headlights of a car going 50,000 mph. Of course, due to the doppler effect, the wavelength of your cars light will be shifted either to the red end of the spectrum, or the blue, depending on the position of the observer..
