Discussion: 1- Define refraction index? What its depending parameters? Value for air and water? 2- Define with physical units and relationships if founded: Critical angle- Compound lens - Parallax eliminating Lens Maker's equation- Total Internal Reflcction (TLR) - Sncll's Law?. 3- What are Real width and Virtual width?. 4- What Optical Density? Is high Mass Density effect?, Explain with exaruples?. 5- Is thickness of media effected to refiaction index?, Why?. 6- What difference between ice and water refaction index? Which larger? Why?. 7- In experiment- part one, can you find refraction index of oil? Why?. 8- Prove sia i, AC 9- Prove AC Real Widtlh 10- prove %3D 5-5 Virted Width

Module 34-2 Spherical Mirrors •6 An object is moved along the 2 central axis of a spherical mirror while the lateral magnification m of it is measured. Figure 34-35 gives m versus object distance p for the range P.= 2.0 cm to p, = 8.0 cm. What is m for p = 14.0 cm? Pa p (cm) Figure 34-35 Problem 6.
