B) A Hydrogen atom initially in its third level, emitted a photon and ends down in its ground state. What must have been the frequency of the photon? Now the electron makes spontaneous absorb and comes back to the third level. What are the possible frequencies of the photons absorbed during this process?
A Hydrogen atom initially in its ground state i.e., n = 1 level, absorbs a photon and ends up in n = 4 level. (a) What must have been the frequency of the photon? Now the electron makes spontaneous emission and comes back to the ground state. (b) What are the possible frequencies of the photons emitted during this process?
Atomic spectra exist because electrons can only transition between well- defined energy levels, and emit photons with those energies. O True O False

A tritiun atom (*H) can undergo spontancous radioactive decay into helium-3 ion (He+) by cmission of a beta particle. The departure of The electron is so fast that to the orbital clectrou the process appears as mply an instantaneous change in the nuclear charge from Z = 1 to Z = 2. I'alculate the probability that the He ion will be left in its ground state.
Using the Boh model of an electron orbiting a nucleus, the angular momentum of Earth's orbit around the Sun is 2.67 x 1040 g m2 s−1. Using the Bohr quantization condition, what is the quantum number n for Earth's orbit? If the Earth transitions from this orbit to n-1 (emitting a graviton, which is the gravitational anagloue of the photon), how much energy would be released? Find the frequency of the graviton.
An electron is in the ground state of the tritium atom for which the nucleus consists of one proton and two neutrons. Suppose the nucleus instantaneously changes into He”, consisting of two protons and a neutron due to a nuclear reaction.

In the equation above, w is called the work function and it is the minimum energy required to dislodge an electron from the metal's surface. The value of w varies from metal to metal, Using Einstein's formula for the energy of a photon, The work function is related to the threshol frequency (and thresk wave length) as follo we obtain the following expression for the kinetic energy of the ejected electrons: hc w = hv.= (KE), = hv - w = h(v-v This result helped Einstein explained observations (1) and (2). Since (KE). = mv must be greater than zero (i.e. m is positive and v is positive), then we know that v must be greater than ve: Also, a plot of (KE). versus v should be linear and the value of h is obtained from the slope of the line! The value of h was expected to be (and found to be) equal to 6.626x10-34 J s! The "appearance" of h in another physical situation suggested that Planck's quantum hypothesis was not that crazy after all. See p from Example 2-1: A domestic microwave employs…
While studying the spectrumn of a gas doud in space, an astronomer magnifies a spectral line that results from a transition from a p state to an s state, She finds that the line at 575.050 nm has actually split into three lines, with adjacent lines 4.70 x 10- nm apart, indicating that the gas is in an external magnetic field. (Ignore effects due to electron spin.) What is the strength of the external magnetic field? O B=3.25 T OB-2.98 T O B=2.79 T O B=3.05 T OB=2.05 T
