" I've shed many tears. But after, I realize, why am I crying? No matter how bad it got, it could be worse. No matter how much you think it's not going to be ok, eventually it will be. You just have to let it be."
EXPECT MORE FROM URSELF THAN FRM OTHERS AS EXPECTATION FRM OTHERS HURTS U WHILE FROM UR SELF INSPIRES U A lot |

when u heat a body it emits radiation
but they have diff intensities
acc to this law product of wavelength corress to max intensity of radiation and temp in kelvin is const
lambda = #
then
#.T = const

everybody is a black body=??
i dont agree with this statement .a balck body purely and surely implies that it absorbs 99.99999% falling on it ,
and all other bodies are not black bodies but bodies which abosorb(or emit) less than this.
if u feel i m worng .plzz correct me. BUT I WANT SOME GOOD EXPLAINATION AND REASON FOR EVERY SENTENCE U HAVE GIVEN.
{my main question, explain how b=always constant for all bodies}
