An X-ray tube operates on 30 kV. The minimum wavelength emitted is h = 6.6 xx 10^(-34) Js, c = 3 xx 10^(8) m/s, e = 1.6 xx 10^(-19) C.

What is the wavelength of light . Given energy =3.03xx10^(-19)J, h=6.6xx10^(-34)JS, c=3.0xx10^(8)m//s ?

The wavelength of most energetic X-rays emitted when a metal target is bombarded by 40 keV electrons, is approximately (h=6.62xx10^(-34)J-sec,1eV=1.6xx10^(-19)J,c=3xx10^(8)m//s) .

Light of wavelength 4000 Å falls on a photosensitive metal and a negative 2 V potential stops the emitted electrons. The work function of the material ( in eV) is approximately ( h = 6.6 xx 10^(-34) Js , e = 1.6 xx 10^(-19) C , c = 3 xx 10^(8) ms^(-1))

The energy of an X-ray photon of wavelength 1.65Å is (h=6.6xx10^(-34)Js,c=3xx10^(4)ms^(-1),ev=1.6xx10^(-19)J)

If 50 kV potential difference is applied across a Coolidge tube, what will be the maximum frequency of X-ray emitted from the tube? h=6.6xx10^(-34)J*s,e=1.6xx10^(-19)C .

What should be the minimum value of potential difference to be applied across a Coolidge tube for production of X-rays of wavelength 0.8 Å ? h=6.62xx10^(-34)J*s,e=1.6xx10^(-19) C

If de Broglie wavelength of an electron is 0.5467 Å, find the kinetic energy of electron in eV. Given h=6.6xx10^(-34) Js , e= 1.6xx10^(-19) C, m_e=9.11xx10^(-31) kg.
