How did the Energy Quicks enter the image in Planck's emission of Planck's Radiation Act?
In planck's radiation energy in the form of of discreate quanta
Value of n can be from 0 to infinity .
So it can be quick enter because energy have many value from 0 to infinite.

h) What was Planck's intention to deduce Planck's law and how did he do it?
For blackbody radiation obeying Planck's distribution law show by direct computation that the energy fluctuation for radiation in a volume V in the spectral interval is given by Einstein's fluctuation formula: Please show all steps (u,v + du) ((AE)2) = V (hvu, + envz uz) dv where u,dv is the corresponding energy density. Show that just the first term would result from Wien's distribution law whereas just the second term would result from the Rayleigh-Jeans distribution law.

(1) Working with Planck's Law [45 pts] Planck's Law describes the intensity (energy per time per area per frequency per angular area) of radiation from a homogeneous, isothermal source: dE 2hc21 Integrating this relation over a spherical hemisphere (outward only) yields the flux density of blackbody radiation from a surface: dE (a) [10 pts] Integrate the above relation over all wavelengths (0 < λ < 00) to derive the total energy flux from a blackbody (the Stefan-Boltzmann Law) dE dtdA...
1.1 Planck's Thermal Radiation Formula (See SQ1) Planck's formula of thermal radiation can be expressed in terms of frequency as df (a) From Eq.(1) (right-hand side), work out the units of u(f,T). Hence, state clearly the meaning (b) From Eq(l), show that the Stefan-Boltzmann law follows, i.e, total energy goes like oT and find an expression for the prefactor σ. Hint: The following integral (that you will see in statistical mechanics course) may be useful e-idr = 15 Optional (No...
Use a computer to calculate Planck's radiation law for a temperature of 3000 K, which is the temperature of a typical tungsten filament in an incandescent light bulb. Plot the intensity versus wavelength. (a) How much of the power is in the visible region (400-700nm) compared with the ultraviolet and infrared? (b) What is the ratio of the intensity at 400 nm and 700 nm to the wavelength with maximum intensity?
Processes at the center of a nearby galaxy cause the emission of electromagnetic radiation at a frequency of 2.95 × 10 13 Hz . Detectors on Earth measure the frequency of this radiation as 2.27 × 10 13 Hz . How fast is the galaxy receding from Earth?
What did the intensity distribution of Blackbodyy Radiation reveal about the energy transmitted by light?
In an MRI, one detects the absorption and emission of radiation as spins flip back and forth in a magnetic field. The energy of the radiation emitted or absorbed when a spin flips is given by: gghB (2) 2m. where g is typically 2, q is the charge of the spinning object, m is its mass, and B is the magnetic field strength. (a) (2 points) A clinical MRI detects a signal from protons flipping up and down. If the...
