Minimum energy required to remove an electron from the ground state of atom is called ................................ nuclear energy ionisation energy atomic energy none of these. Name spectral series of hydrogen atom lying in visible region Balmer series Paschen series Lyman series P-fund. Which of the following is the best way to increase intensity of X-rays Increase potential between cathode and anticathode Make anticathode more positive Make Cathode more positive Increase current of filament to increase its temperature. Name the spectral series of hydrogen which lies in ultraviolet region. Balmer Lyman Paschen Brackett. Why there is maximum frequency for X-ray produced by an X-ray tube at a certain voltage? Maximum frequency is obtained when incident electron loses all its energy in multiple collision with target atom. Maximum frequency is obtained when incident electron loses part of its energy in a single collision with target atom. Maximum frequency is obtained when incident electron loses all its energy in a single collision with target atom. None of the above. Which gives the relation between maximum frequency of X-ray produced by coolidge tube and potential difference V? f [max] = V / eh f [max] = h / eV f [max] = e V / h None of these. Energy of hydrogen in second excited state is -1.5 eV -13.6 eV -3.4 eV None of these. Energy of X-ray depends upon Material used as anticathode Temperature of filament Energy of striking electron None of these. Which differentiates the best between X-rays and gamma rays X-rays are due to transition in atomic energy level whereas gamma rays are not due to any type transition. X-rays are not due to any type of transition whereas gamma rays are due to transition in the nuclear energy level. X-rays are due to transition in nuclear energy level whereas gamma rays are due to transition in the atomic energy level. X-rays are due to transition in atomic energy level whereas gamma rays are due to transition in the nuclear energy level. Which is preffered for use in medical purpose to view our internal structures? Soft X-rays Hard X-rays Both soft and Hard X-rays Neither soft or hard X-rays we have special type of X-rays for medical purpose.
