Rayleigh entropy
WebSep 7, 2024 · The negative sign here reveals that the number of modes decreases with increasing wavelength. Now to get the number of modes per unit volume per unit wavelength, we can simply divide by the volume of the cubical cavity. Dividing above term by L 3 on each side gives.
