- Blackbody is a theoretical object that absorbs 100% radiation.
- Carbon in graphite form absorbs all but about 3% of incoming radiation.
- At a particular temperature the black body would emit the maximum amount of energy possible for that temperature. This value is known as blackbody radiation.

- Maximum wavelength emitted by a black body radiator is infinite
- Blackbody emits a definite amount of energy at each wavelength for a particular temperature.

Fig 1. Black Body Radiation Plot

- According to Figure 1, the curve touches the x-axis at infinite wavelength. This shown that blackbody does radiate energy at every wavelength.
- At 5800K the peak wavelength (wavelength that emits most energy) is about 5e-7 m.

Fig 2. Black Body Radiation Curves

- Figure 2 shows how the blackbody radiation curves change at various temperatures.
- As the temperature increases, the peak wavelength emitted by the blackbody decreases.
- As the temperature increases, the total energy emitted increases, because the total area under the curve increases.

With classical physics, we are certain that we can determine the future by analyzing the data from the past and the present. However, the discovery of quantum mechanics shown that even with all necessary information, the future remains unknown.

In the early 1900, four important events had revolutionized science and the way we think about the world around us. They are Planck’s solution to the blackbody radiation, Einstein’s explanation of the photoelectric effect, the Bohr model of the atom, and the de Broglie wavelength of material particles
