Atomic Physics: Compute frequency of photon in a certain nuclear reaction

A photon has an energy of 2.4eV. Find its frequency and its wavelength.

A collimated beam of 200 keV gamma radiation delivers an incident energy flux of 2 J m^-2 s^-1 to a lead shield 1 g cm^-2 thick. a. What is the incident photon flux in photons cm^-2 s^-1? b. What is the rate of energy absorption in the shield in both erg g^-1 s^-1, J kg^-1 s^-1 and Gy s^-1

Please help with the following physics problem. The lowest energy visible light photon is the longest wavelength at the red end of the light spectrum. How many times greater is this energy than that of a typical microwave photon with a wavelength of 10^7 nm?

Please help with the following problems. (1) Suppose that a photon has energy of 5 x 10 -19 J. (five times ten to the negative 19th Joule) What's the wavelength of this photon? What is its frequency? (2) The photon in the above problem strikes a metal plate that has a work function of PHI = 3 x 10 ^ -19 J. What's the max

What is the energy of a photon that has a wavelength of 9.0 m?

6. Electron interactions were characterized by a ratio "b/a". The ratio "b/a" represents: a) Orbital electron distance to nuclear radius b) Photon wavelength to atomic radius c) Impact parameter to atomic radius d) Orbital electron radius to nuclear radius 7. The electron-electron interaction that results in brehmsstr

(a)Energy is required to separate a nucleus into its constituent nucleons. This energy is the total binding energy of the nucleus. In a similar way one can speak of the energy that binds a single nucleon to the remainder of the nucleus. For example, separating nitrogen ^14/7N into nigtogen ^13/7N and a neutron takes energy equal

Violet light has a wavelength of about 410 nm. What is its frequency? Calculate the energy of one photon of violet light. What is the energy of 1.0 mol of violet light photons? Compare the energy of photons of violet light with those of red light. Which is more energetic and by what factor? Frequency of violet light:____

Calculate the classical frequency for the light emitted by an atom. To do so, note that the frequency of revolution is v/2pir, where r is the Bohr radius. Show that as n approches infinity in f= 2pi2mk2e4/h3 times 2n-1/(n-a)2 n2 the expression varies as 1/n3 and reduces to the classical frequency.
