TYPICAL NUMERIC QUESTIONS FOR PHYSICS I REGULAR QUESTIONS TAKEN FROM CUTNELL AND JOHNSON ATOMIC SPECTRA Science concepts. The student knows simple examples of quantum physics. The student is expected to: (A) describe the photoelectric effect; and (B) explain the line spectra from different gas-discharge tubes. 1. J. J. Thomson's model of an atom A) had electrons embedded in some kind of fluid that contained most of the mass of the atom. B) held that the fluid containing most of the mass of the atom had enough positive charge to make the atom electrically neutral. C) failed to predict the observed frequencies for any atom. D) depended upon electric forces to produce stability. E) All of these are correct. 2. The wavelength of the visible line in the hydrogen spectrum that corresponds to m = 4 in the Balmer equation is A) 656 nm B) 486 nm C) 434 nm D) 410 nm E) None of these is correct. 3. The wavelength of the visible line in the hydrogen spectrum that corresponds to m = 5 in
