Wien displacement law:
For blackbody, the product of the wavelength equivalent to the maximum radiancy and the thermodynamic temperature is a constant, the Wien displacement law constant. Consequently, as the temperature grow the maximum of the radiant energy shifts to the shorter wavelength (higher frequency and energy) end of the spectrum.
50 gm of an optically active substance is dissolved in 100 ml of water. A plane polarised light, when passing through 30 cm of the solution, suffers a rotation of 390 in it's plane
