Why blackbody spectrum is continuous?

Whenever a blackbody emits radiation, it corresponds to an electron jumping from higher energy state to a lower energy state and because of this an electron in excited state has a very large number of ‘energy levels below’, it can jump into any of the empty states giving a continuous spectrum.

What is a black body on what factors does the radiation emitted from it depend?

Black body radiation is the emission of electromagnetic energy by an object which is in a thermodynamic equilibrium. The blackbody emits an amount of energy depends on its temperature, with ideal blackbody absorbing and re-emitting all the incident radiations it receives at any wavelength.

What do you understand by black body radiation?

An object that absorbs all radiation falling on it, at all wavelengths, is called a black body. When a black body is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. Its emission is called black-body radiation.

What does black body radiation tell us?

A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none. Planck’s Law of blackbody radiation, a formula to determine the spectral energy density of the emission at each wavelength (Eλ) at a particular absolute temperature (T).

How does black body radiation differ from reflected radiation?

Black bodies it would absorb all the radiation that falls on it. it would not reflect or transmit any radiation.

What does Planck’s law predict?

Planck’s law is a formula for the spectral radiance of an object at a given temperature as a function of frequency (Lf) or wavelength (Lλ). It has dimensions of power per solid angle per area per frequency or power per solid angle per area per wavelength….energy is quantized.
