How many IR photons with a 1.23 mm wavelength are needed to have the same energy as one photon of 205 nm UV light?
Nuclear fusion reactions at the center of the sun produce gamma-ray photons with energies of order 1 MeV (106 eV). By contrast, what we see emanating from the sun's surface are visible-light photons with wavelengths of order 500 nm. A simple model that explains this difference in wavelength is that a photon undergoes Compton scattering many times - in fact, about 1026 times, as suggested by models of the solar interior - as it travels from the center of the...

1.. Suppose that you shine light of energy 1050 kJ/mol on an H atom in the ground state. What happens to the light and to the electron? Group of answer choices a. The light is not absorbed and the final energy of the electron is -1312 kJ/mol. b.. The light is absorbed and the final energy of the electron is −328 kJ/mol. c.. The light is not absorbed and the final energy of the electron is −1050 kJ/mol. d.. The...
If a 120-W lightbulb emits 25% of the input energy as visible light (average wavelength 550 nm) uniformly in all directions. Part A How many photons per second of visible light will strike the pupil (4.0 mm diameter) of the eye of an observer 1.0 m away?
A laser pulse with wavelength 515 nm contains 4.40 mJ of energy. Question: How many photons are in the laser pulse? Can someone please walk me through the steps? I have tried to solve this multiple times, but the 2 answers I thought were for sure it are A: 2.21 x 10^22 photon B: 4.40 Joules X (1 photon/3.860x10^-19 Joules) They were both wrong.
At our distance from the Sun, the intensity of solar radiation is 1370 W/m^2 . As discussed in class and in the textbook, the temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the effect of absorption of infrared radiation by the surface so as to make the surface temperature of the Earth higher than if it were airless. The average global surface temperature of the Earth is ~288 K. Calculate the surface...
