As Einstein found out in his Nobel winning experiment,
red light,no matter how bright does not eject photoelectrons,
it will not produce a current.......however UV light ejects the
most photoelectrons & current.
As in the chakra system red is the lowest vibration while
purple,UV light,is the highest.....Einstein was thousands of
years late to the party......we already knew this,it has been
expressed in & a part of many ancient religions.
There.....i have tied in Quantum mechanics with Religion!
oops starred myself by mistake!
