Radiosity of a area for each device frequency or wavelength. The latter is usually calculated in W⋅m⋅nm. This is sometimes also confusingly known as "spectral intensity". If your beam of light will not be orthogonal (or somewhat ordinary) to your boundary, the adjust in wavelength leads to a change https://garrettvenve.shoutmyblog.com/37900956/details-fiction-and-prefab-house
