Consider radiation of wavelength 4000.0 Angstroms, at a temperature of 3000.0 K. A) Using the Rayleigh-Jeans law, calculate the energy per unit volume per unit wavelength. Use Joules and meters. B) Using the Planck radiation law, calculate the energy per unit volume per unit wavelength. Use joules and meters. The equations given were S= (8?kT)/(?^4) and S=[(8?hc)/(?^5)][1/(e^(hc/?kT)-1)]
For A I got 4.067*10^7 and for B I got 3035.48
Also, I tried to calculate the units throughout and I got Joules/meter for A and Joules for B. I am not sure where I messed up.

KURSVLOEBEUR Question 4 [20 marks] (a) What particular aspect of the Rayleigh-Jeans Law, the classical theory of blackbody radiation, caused it to fail to explain the blackbody radiation spectrum? (b) What aspect of the Boltzmann probability distribution used in formulating Planck's Law of blackbody radiation allows it to avoid the problem that caused the classical model to "crash and burn" i.e. not match experiment? (c) In a low energy electron diffraction (LEED) experiment, 62 eV electrons are scattered from the...
Ultraviolet radiation falls in the wavelength region of 1.00x10-8 to 1.00x107 meters. What is the wavelength of ultraviolet radiation that has an energy of 1.99x10-20 kJ/photon? Wavelength = 9.98x10^-6 m Submit Answer Retry Entire Group 9 more group attempts remaining Compare the de Broglie wavelength of a bullet moving at 700 miles per hour (313 m/s) to that of an alpha particle moving at 3.40x107 miles per hour (1.52x107 m/s) and an electron with a speed of 1.30x107 miles per...
To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol λ (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given the symbol...

Numbers 8 & 9 Please! Thank you! Consider a region of the atmosphere of volume 25 dm3, which at 20°C contains about 1.0 mol of molecules. Take the average molar mass of the molecules as 29 g mol1 and their average speed as about 400 m s1. Estimate the energy stored as molecular kinetic energy in this volume of air What is the minimum energy that a bird of mass 25 g must expend in order to reach a height...
