Ultraviolet light of wavelength 300 nm and intensity 1 ~W / m ^2 falls on the surface of a photosensitive material. If one percent of the incident photons produce photoelectrons thIn an X ray tube the electrons are expected to strike the target with a velocity that is 10 % of the velocity of light. The applied voltage should beWhich of the following curves represents spectral distribution of energy of black body radiation?The force of attraction between the positively charged nucleus and the electron in a hydrogen atom is given by f=k e^2 r^2 . Assume that the nucleus is fixed. The electron, initialThe photoelectric threshold wavelength of tungsten is 230 nm . The energy of electrons ejected from its surface by ultraviolet light of wavelength 180 nm is:The energy of the characteristic X-ray photon in a Coolidge tube comes fromThe maximum wavelength that can ionize a hydrogen atom initially in the ground state isThe wavelength of the waves associated with a proton and a photon are the same. Therefore, the two have equal Full Dual Nature of Matter list All Olympiad workbook PYQs
