Wiens Law `(lambda_(m))` corresponding to which energy emitted per sec per unit area by a perfectly black body (surface) is maximum is inversly proportional to the absolute temp (T) of the black body .
`lambda_(m)prop(1)/(T)orlambda_(m)=(b)/(T)`
Where b is a constant of proportionality and is called Wein's constant `b=2.898xx10^(-3)mK` . Is the statement True?
