Black Body Radiation Experiment

Classical physics can be used to derive an equation which describes the intensity of blackbody radiation as a function of frequency for a fixed temperature the result is known as the rayleigh jeans law. The radiation detected outside the hole will be a sample of the radiation inside the box so some analysis is required to understand whats happening inside the box.

Black body radiation experiment. Black body radiation is the thermal electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment emitted by a black body an idealized opaque non reflective body. Blackbody radiation blackbody radiation or cavity radiation refers to an object or system which absorbs all radiation incident upon it and re radiates energy which is characteristic of this radiating system only not dependent upon the type of radiation which is incident upon it. It does not only absorb radiation but can also emit radiation.

Blackbody radiation is a cornerstone in the study of quantum mechanicsthis experiment is what led to the discovery of a field that would revolutionize physics and chemistry. Quantum laser pointers brings you the infamous double slit experiment right in the palm of your hand. A blackbody is an idealized object which absorbs and emits all frequencies.

Jerry heasley recommended for you. A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation regardless of frequency or angle of incidence. In 1801 english physicist thomas young performed this experiment to determine if light was a.

It has a specific spectrum of wavelengths inversely related to intensity that depend only on the bodys temperature which is assumed for the sake of calculations and theory to be. If light hits the hole it will enter the box and theres little chance of it bouncing back out. The name black body is given because it absorbs radiation in all frequencies not because it only absorbs.

Therefore in this case the hole not the box itself is the blackbody. Quantum mechanics gives a more complete understanding of the fundamental mechanisms at the sub atomic level.
