Does traveling towards a light source at a significant fraction of c mean that you will infact see the light source sooner than say someone who is stationary at the point you began traveling at the fraction of c from? Say you are traveling towards a light source a light year away, will you see...

thebigstar25, i think you are forgetting that we are dealing with an extrinsic semiconductor, the formula you have presented is used in calculating conductivity of an intrinsic semiconductor. this problem can simply be solved where the assumption is made that all the electrons are accepted so...

Homework Statement The number of vacancies in a metal increases by a factor of six when the temperature is increased from 800K to 1000K. Calculate the energy for vacancy formation assuming that the density of the metal remains the same over this temperature range. Homework Equations Nv= N...
