Lorenz's long reduction and Inverse Square Law - 07/09/14 11:24 AM
Bulb ---> u .............observer B ---> 2u
bulb ---------> 2u ........observer B' ---------> 2u
*observer A
We have long reduction for observer A what about Brightness
more smaller bulb and the same power = more brightness point
more biger bulb and the same power = more darkness bulb
Space around observers = medium for light
inside medium we have some joules nomber
Brightness it is function ( Size ( mm^2 ) and joules no )
Brightness it is additional inforamtion
Observer B' or B is able recognize own motion without outside object observation only measure Joules/mm^2 and Size
