Characteristic X-rays are produced due to ....

A

transfer of momentum in collision of electron with target atoms

B

transition of electron from higher to lower electrons orbits in an atom

C

heating of target

D

transfer of energy in collision of electrons with atoms in the target.

Text Solution

Verified by Experts

The correct Answer is:
B
When the high energy electron hits the target and takes out an electron from the inner orbit there is a possibility of an outer electron to fall down to fill up that vaccancy and when such a transition of electron takes place from a higher energy level to a lower energy level, the difference of energy `(E_(2)-E_(1) = hv)` between two levels is given in the form of radiation known as characteristic X-rays.

    How gamma rays are produced ?

    Characteristic X-rays of frequency 4.2xx10^18 Hz are produced when transitions from L-shell to K-shell take place in a certain target material. Use Mosley's law to determine the atomic number of the target material. Given Rydberg constant R =1.1xx10^7 m^(-1) .

    Statement-1 If the accelerating potential in an X-ray tube is increased, the wavelength of the characterstic X-rays do not change. because Statement-2 When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.
