Can `L_alpha` X-ray of one material have shorter wavelength than `K_alpha` X-ray of another?

Show that the frequency of K_beta X-ray of a material equals the sum of the frequencies of K_alpha and L_alpha X-rays of the same material. (##HCV_VOL2_C44_S01_006_Q01##)

Write range of wave length of X - rays.

If there times of lambda_(min) of continuous X- ray spectrum of target metal at 40 kV is some as the wavelength of K_(alpha) line of this metal at 30 kV , then determine the atomic number of the target metal.

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.

If lambda_(Cu) is the wavelength of K_(alpha) X-ray line of copper (atomic number 29 ) and lambda_(Mo) is the wavelength of the K_(alpha) X-ray line of molybdenum (atomic number 42 ),then the ratio lambda_(Cu)//lambda_(Mo) is close to

There are materials which absorb photons of shorter wavelength and emit photons of longer wavelength .Can there be stable substances which absorb photons of larger wavelength and emit light of shorter wavelength.

The wavelength of K_(alpha) line for an element of atomic number 43 is lambda . Then the wavelength of K_(alpha) line for an element of atomic number 29 is

Which of following statements are correct ? (1) Wavelength of microwaves is greater than that of UV rays. (2) Wavelength of infrared radiation is less than that of UV rays. (3) Wavelength of microwaves is less than that of infrared waves. (4) Gamma rays have shortest wavelength in electromagnetic spectrum.

The Ka X-ray of molybdenum has wavelength 71 pm. If the energy of a molybdenum atom with a K electron knocked out is 23:32 keV, what will be the energy of this atom when an L electron is knocked out?
