Final Exam—Physics Lab 204 Spring 2016 • Memorize the following equations: Ohm’s Law, Lens Equation •Be able to answer all quiz questions. •Lab 3-5 (Practical) Be able to set up a series or parallel circuit (with 2 resistors) and measure the current/voltage in the circuit and the current/voltage in the resistors. •Lab 4 (Practical or Written) Be able to solve for the equivalent resistance and the voltage and current for each resistor in a series or parallel circuit. •Lab 8 (Practical or Written) Be able to use the parallax method to trace the reflected rays from a mirror and locate the position of the image or measure the incident and reflected rays. •Lab 8 (Practical) Be able to use the parallax method to trace the refracted rays through a slab of glass. Be able to measure the appropriate angles to calculate the index of refraction. •Lab 9 (Practical) Be able to set up a 1-lens system and determine the focal length and magnification of the lens. •Lab 5/7 Describe how a galvanometer works. •Lab 7 Be able to describe how a tangent galvanometer works and is used to measure the Earth’s magnetic field. •Lab 7 Given data for current and deflection angle, be able to calculate the Earth’s magnetic field (equations & graph paper provided) •Lab 7 Describe the purpose of a double pole, double throw switch. Given a schematic, be able to sketch how it would be used in a circuit. •Lab 8 Be able to sketch the path of a ray of light and calculate or measure the incident or refracted angles as it travels through: a) Flat slab of glass b) Triangular prism (67M and 45T sections only) •Lab 9 Be able to describe, draw a diagram, of and calculate spherical aberration of a lens. (given equation for SA) •Lab 9 Be able to use the lens equation to calculate the image distance, object distance, or focal length. Also, be able to calculate the magnification. Be able to do the same for a 2-lens system. •Lab 9/10 Be able to calculate the magnification of a single lens, compound microscope, and telescope. (Equations will be given, but not labeled by instrument.) •Lab 10 Be able to describe and/or sketch a compound microscope and telescope. Know the differences between the two such as: where the object and image are located and where the lenses are located relative to their focal lengths. •Lab 11 Identify an emission spectrum as either hydrogen or helium. •Lab 11 Describe how stars are classified into their spectral types and physical properties of stars related to their spectra. •Lab 11 Be able describe how a diffraction grating works to separate light of different wavelengths. (Thursday 1R section will not be responsible for Lab 11 material)
