PHYS375 Review Exam will be in two parts: written and in lab Both parts will be open book and notes

Exam Details Written – Four questions limited to the areas to be discussed next Lab – About four components you will have to measure and document. You will not have to provide a report but you lab notes should be clear evidence you actually performed the experiment.

Theoretical Things to Know 1.Refraction at surfaces – Snell’s law; 2.Critical angles –    (Brewter’s angle) and  C  total internal reflection); 3.ABCD matrix method with thin lenses; 4.Optical path length; 5.Interference and/or diffraction (Fraunhofer) from single and double slits; 6.Simple spectroscopic instruments – prism and grating spectrometerDispersion (spreading) of light by prisms and gratings;

Snell’s law Problems: 2-5, 2-7, 2-8 and 3-6

ABCD matrix Only focus on thin lenses and combinations. Must know matrix multiplication and the meaning of various elements. Must be able to determine the cardinal points Example problems: 18-9, and applied to 3-24.

Fraunhofer Diffraction Must know how to calculate the field from the diffraction integral. Know what the diffraction patterns look like for single and double slits, rectangular slit with diffraction in two directions and circular slits. Must know the relationship between the size of the aperture and the diffraction angle. Problems: 2 & 3 HW6, 11-9, 11-12

Interference Problems: 7-1, 7-6 would be good to know.

Optical Instruments Spectrometers with gratings and prisms Gratings problems: 12-1 and 12-3 for example. Prism problems: 3-7 Michelson interferometer problems: 8-3 and 8-5.

Lab Things to Know Should be familiar with all seven (including the 0 th lab). How to keep a record of what you have done. I will be looking for evidence to convict you of having done the lab. – Saying “I aligned the laser” without providing any detail of exactly how will garner very few, if any, points! – Provide a description of what was done with sketches.

Lab (cont.) You will have several pieces of optics to identify – e.g., – blocks of optical material for which you will have to determine n, – apertures for which you will have to determine their size w/o measuring w/ microscope, – Lenses for which you will have to determine f and n, etc. You will be able to measure with techniques you’ve learned this semester.
