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 thWhich 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 equalThe mass of an electron can be expressed as(where c is speed of light in vacuum) (where c is speed of light in vacuum) Full Dual Nature of Matter list All Olympiad workbook PYQs
