Irradiance of a surface area for each device frequency or wavelength. The conditions spectral flux density or more confusingly "spectral intensity" also are made use of. Non-SI units of spectral irradiance include things like Jansky = 10 W⋅m⋅Hz and solar flux unit (1SFU = 10 W⋅m⋅Hz). In historical India, https://paulg208dlu6.glifeblog.com/profile
