Question 3. Wave picture of light failed to explain. (a) the photoelectric effect (b) polarization of light (c) diffraction of light (d) interference of light Answer Question 4. Heliocentric theory proposed by Nicolas Copernicus was (a) replaced by circular orbits to fit the data better (b) replaced by elliptical orbits to fit the data better (c) replaced by elliptical orbits to fit the taste of new rulers of Italy (d) replaced by parabolic orbits to fit the data better Answer Question 5. Just as a new experiment may suggest an alternative theoretical model, a theoretical advance may suggest what to look for in some for in some experiments. Which of the following experiments can be considered to support this claim? (a) Davisson and Germer Experiment (b) experimental discovery of positron (c) scattering of alpha particle or the gold foil experiment (d) Michelson Morley experiment Answer Question 6. The scientific method is (a) a prescribed method for investigating phenomena, acquiring new knowledge… (b) A procedure for proposing new hypothesis (c) a body of techniques for investigating phenomena, acquiring new knowledge… (d) A method for proposing new theories. Answer Question 7. A scientific theory (a) cannot be changed but can be reformulated (b) is fixed once and for all because it is logical (c) is changed to suit new fashion among scientists (d) can be revised if required to fit new phenomenon or data
With the Wave theory, the phenomena of Reflection, Refraction, and Interference of light can be explained, but it fails to explain Diffraction and Polarization of light.
