Chapter 6: Q15DQ (page 1474)

In the process of internal conversion, a nucleus decays from an excited state to a ground state by giving the excitation energy directly to an atomic electron rather than emitting a gamma-ray photon. Why can this process also produce x-ray photons?

Short Answer

Expert verified

K-Because the emitted atomic electron collides with shell electron releases enough energy to escape from its level or escape from the atom. The release in energy causes a vacancy in the K-shell and an electron available in the outer falls into the vacancy causing a much lower level.

Step by step solution

01

Define the energy.

The energy Eof a photon is inversely proportional to the wavelength 位of photon and directly proportional to the frequency fof wave.

E=hfE=hc位

Where, the value of Planck鈥檚 constant h=6.626脳10-34J路s.

02

Explanation.

K-When the emitted atomic electron collides with shell electron releases enough energy to escape from its level or escape from the atom. The release in energy causes a vacancy in the K-shell and an electron available in the outer falls into the vacancy causing a much lower level.

Therefore, emits the energy as a photon, and produce x-rays.

In an experiment involving the photoelectric effect, if the intensity of the incident light (having frequency higher than the threshold frequency) is reduced by a factor of 10 without changing anything else, which (if any) of the following statements about this process will be true? (a) The number of photoelectrons will most likely be reduced by a factor of 10. (b) The maximum kinetic energy of the ejected photoelectrons will most likely be reduced by a factor of 10. (c) The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 10. (d) The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 110. (e) The time for the first photoelectron to be ejected will be increased by a factor of 10.

You are standing on a train platform watching a high-speed train pass by. A light inside one of the train cars is turned on and then a little later it is turned off. (a) Who can measure the proper time interval for the duration of the light: you or a passenger on the train? (b) Who can measure the proper length of the train car: you or a passenger on the train? (c) Who can measure the proper length of a sign attached to a post on the train platform: you or a passenger on the train? In each case explain your answer.

Explain why the cosmological principle requires that H0 must have the same value everywhere in space, but does not require that it be constant in time.

In a photoelectric-effect experiment, which of the following will increase the maximum kinetic energy of the photoelectrons? (a) Use light of greater intensity; (b) use light of higher frequency; (c) use light of longer wavelength; (d) use a metal surface with a larger work function. In each case justify your answer.
