Why does the two-mile linear accelerator atStanford University in California “appear” tobe less than a meter long to the electrons thattravel in it?A meter stick moves parallel to its axis withspeed of 0.9crelative to you.What would you measure for the lengthofthestick?Thespeedoflightis1.Length contraction reduces the apparentlength.correct2.Time dilation makes the lifetime of elec-trons longer.3.The decrease in volume makes the elec-tron smaller.4.Electrons travel faster than the speed oflight.Explanation:For the moving electron, length contractionreduces the apparent length of the 2-mile longtube.Since electrons move with nearly thespeed of light, the contraction is very signifi-cant.keywords:
