Diffuse Radiation Surface:

A diffuse radiation surface is a surface that emits or reflects radiation equally in all directions. The radiation emitted or reflected from a diffuse radiation surface is not dependent on the angle of observation or the wavelength of radiation.

Radiation Intensity:

Radiation intensity is the amount of radiation energy per unit time per unit solid angle. The radiation intensity of a diffuse radiation surface is independent of angle, which means that the amount of radiation energy emitted or reflected from the surface is the same in all directions.

Emissive Power:

Emissive power is the amount of radiation energy emitted by a surface per unit time per unit area. The emissive power of a diffuse radiation surface is independent of angle, which means that the amount of radiation energy emitted by the surface is the same in all directions.

Wavelength:

The wavelength of radiation refers to the distance between two consecutive peaks or troughs of a wave. The radiation emitted or reflected from a diffuse radiation surface is not dependent on the wavelength of radiation.

Conclusion:

In conclusion, a diffuse radiation surface has radiation intensity independent of angle, emissive power independent of angle and wavelength.
