Why lines changing wide and Hz ( 24h test )


HD camera constant Hz
LED constant Hz
C- speed = constant



What is variable in above test ?

CAMERA OBSCURA - how much time need light to go from object to box ?
angles inside hole ? do we have constant size of picture "opposite wall in box "?








IMPORTANT FACT
INVERTED SQUARE LAW

More far from place where signal started = lower intensity of signal
( "lower brightness" )
1R = X , 2R = X/4 , 3R = X/9
X- brightness, R- radius

the same energy portion but different area


DURING SHORT TIME LIGHT MADE DISTANCE "L1"
HOW MANY LUMENS and PER HOW BIG Area will rgister astronomers ?




NOT EXIST C + V !!! LIGHT IS GOING ISOTROPY RESPECT TO POINT WHERE SIGNAL STARTED BELOW DOPPLER + INVERTED SQUARE LAW

Before study belwo picture please read about TOLMAN'S TEST
