Irradiance of a area for each device frequency or wavelength. The terms spectral flux density or more confusingly "spectral depth" are used. Non-SI units of spectral irradiance involve Jansky = ten W⋅m⋅Hz and photo voltaic flux unit (1SFU = ten W⋅m⋅Hz). On the flip side,there happen to be many https://larryt752pyh0.wikiap.com/user
