Hi guys,
could you concretely explain me (also with a simple example) the difference between blackbody emissive power (sometimes found as e'λb) and blackbody radiation intensity ($i^{'}_{λb}$)? and which the difference between a diffuse surface and a surface that follows the Lambert law?

Thank you in advance. Tell me if something isn't clear.
