Irradiance of a surface area for every device frequency or wavelength. The terms spectral flux density or more confusingly "spectral intensity" also are used. Non-SI units of spectral irradiance incorporate Jansky = ten W⋅m⋅Hz and photo voltaic flux unit (1SFU = 10 W⋅m⋅Hz). Equally as light passing through the https://ghomsheif197ajs5.livebloggs.com/profile
