Unformatted text preview: . 86 < 9 (6). Correct answer is C The existance of sharp spectral lines was the major motivation behind the Bohr model (7). Correct answer is A Light is emitted when at atom transitions from an excited state to a dierent state, lower in energy. (8). Correct answer is C Electrons can easily be given enough kinetic energy such that their de Broglie wave-length will be well below the wavelength of visible light. This leads to much greater resolution. 2 (9). Correct answer is A This atom has a completely lled n=2 level and hence is probably inert. (10). Correct answer is B By energy conservation, KE = 6.4 - 13.6/4 =3 ev...
