A blackbody, which is an âidealâ or âperfectâ emitter (that means its emission properties do not vary based on location or the composition of the object), emits a spectrum of light with the following properties: The hotter the blackbody, the more light it gives off at all wavelengths. That is, if you were to compare two blackbodies, regardless of what wavelength of light you observe, the hotter blackbody will give off more light than the cooler one.
Blackheads constitute of sebum â skin oil â that is trapped in skin pores and are often associated with enlargement of nose pores. When the naturally yellowish sebum gets exposed to air, it oxidizes and becomes black in color. The black plug in the blackheads can make your pores appear large. While cleaning the nose to get rid of excess sebum can help to reduce the formation of blackheads and reduce the size of pores, excessive cleaning is counterproductive as it encourage increased production of sebum.
