1. Briefly discuss the determination of the Fresnel reflection and transmission coefficients for an obliquely incident wave on a dielectric interface.
2. What is total internal reflection? Discuss the nature of the reflection coefficient and the manner in which the boundary condition is satisfied for an angle of incidence greater than the critical angle for total internal reflection.
3. What is the Brewster angle? What is the polarization of the reflected wave for an elliptically polarized wave incident on a dielectric interface at the Brewster angle? Discuss an application of the Brewster angle effect.
4. Discuss the principle of optical waveguides by considering the dielectric slab wave- guide.
An aluminum rod 10.0cm long and a steel rod 80.0cm long are combined to form one rod with a total length of 90.0cm. The initial temperature of both rods is 15 degrees celcius. The expansion coefficient of aluminum is 2.4*10^5 and the expansion coeffi..
