the book that i am reading right now quotes this, ''imagine a lightbulb illuminating a room. the light spreads out in a sphere. the strength of the light is diluted across this sphere. thus, if you double the radius of the sphere, then the light is spread out over the sphere with four times the area. IN GENERAL IF A LIGHT BULB EXISTS IN N DIMENSIONAL SPACE, THEN ITS LIGHT IS DILUTED ACROSS A SPHERE WHOSE AREA INCREASES AS THE RADIUS IS RAISED TO THE N-1 POWER. could you explain the maths behind the statement in bold letters. the book is called PARALLEL UNIVERSES By MICHIO KAKU. Thankyou!
Re: can you help with the maths behind an explanation of lightdilutinginasphere
