All of the values in this table were calculated by means of Wien’s equation with the exception of the last column, headed “5000x10-5” and that was calculated by means of Planck’s equation. The values show the correct relationships for different wave-lengths at a single temperature, and between different temperatures if multiplied by the factors which are placed at the heads of the several columns.
