let I=INTENSITY
E=ENERGY POSESSED BY PHOTON
A=PERPENDICULAR AREA OF INTERACTION..
t=TIME
p=MOMENTUM OF PHOTON....P=POWER OF BEAM
C=SPEED OF LIGHT
x=%of light absorbed
f=force
I=dE/(Adt)
>dE/dt=IA
NOW....E=pc
>dE/dt=cdp/dt( c is const)
case 1:complete absorb
f1=xdp/dt=dE/(cdt)=IA/c
case2:complete reflect
f2=(100-x)*2*dp/dt.........(*2 bcoz of momentum conservation)
=2IA/C
now total force exerted....F=f1+f2
={x(IA/C)+2(100-x)IA/C}/100
SO GENERAL FORMULA......
F=P/C{[200-x]/100} here P=IA/C=POWER OF BEAM....NOT MOMRNTUM...
