any electron will be emitted if i use a black body as a metal target in photoelectric effect experimant and why??

hasanhabibul said:why radiation vs wavelength curve of plack radition formula become lower after reaching a certain amount of energy?is it related to threshold frequency or anything else please explain me.
hasanhabibul said:when emw incident on a metal(including black body)..the atoms of the metal gains the energy of hmeu..and become excited and try to go the upper level continously.it seems as if there creates a random movemnet of electron inside the atom so i think but not sure a lot of probability to get off a electron from the metal..and creates current like photoelectric effect.so i asked u if i used a black body as a metal target the same thing will happen or not??and u said not..but i am still unsure.please explain me.
A blackbody is an idealized object that absorbs and emits all wavelengths of electromagnetic radiation with 100% efficiency. In the photoelectric effect, a blackbody is used as a source of light to shine onto a metal surface in order to observe the emission of electrons.
The temperature of the blackbody determines the energy of the photons it emits. Higher temperatures result in a larger number of high-energy photons, which can cause more electrons to be emitted from the metal surface in the photoelectric effect.
No, a blackbody can emit a wide range of wavelengths in the electromagnetic spectrum, including infrared and ultraviolet. The specific wavelengths emitted depend on the temperature of the blackbody.
The intensity of the light, or the number of photons per unit area per unit time, affects the number of electrons emitted in the photoelectric effect. A higher intensity of light results in a higher number of electrons being emitted from the metal surface.
Yes, the color, or wavelength, of the light from the blackbody does affect the photoelectric effect. Different wavelengths of light have different energies, and only photons with enough energy can cause the emission of electrons. This is why different metals have different thresholds for the photoelectric effect, as they require different energies of photons to emit electrons.
