Irradiance of a surface for each unit frequency or wavelength. The conditions spectral flux density or even more confusingly "spectral depth" also are employed. Non-SI units of spectral irradiance incorporate Jansky = ten W⋅m⋅Hz and photo voltaic flux unit (1SFU = 10 W⋅m⋅Hz). In historical India, the Hindu colleges https://carolz086ziq5.vigilwiki.com/user
