Δp=mΔV
Δp=m2Vcos thetha
Ramanarrora:
Add the cos theta component it will come 2Vcos theta
Don't use alternate interior angle method use component method
Resolve the velocity vector
I know but if we use alternate angles property when the light is incident to the plane, its components comes out -vcostheta j and vsinthetaî and if we take componets of reflected ray then by alternate angles it comes out to be -vcosthetaj and -sinthetaî then the cos and cos will cancel out then na
Ya light incident nahi kar rahi ha
It's a ball of mass m
okay sir I'm not getting it
let it be
Theta ka pass wala cos hota ha
woh toh pata hai
