12-8. Show that the coefficient of reflection R and the coefficient of transmission T are both equal to 0.5 at normal incidence on the interface between two dielectrics if the ratio of the indexes of refraction is 5.83.

Step 1
Step 1: Recall the Fresnel equations for reflection and transmission coefficients at normal incidence: R = ((n1 - n2) / (n1 + n2))^2 T = 1 - R where n1 is the index of refraction of the incident medium and n2 is the index of refraction of the transmitted medium. Show more…

When unpolarized light is passed through two polarizing filters in succession, its intensity is decreased by 87.5%. Determine the angle between the transmission axis of the two filters.

48. The condition for total polarization, at Brewster's angle, for a reflected beam from the interface between two media is that the reflected beam and the refracted beam are perpendicular to each other (see Figure 23.22). Use this information to determine a formula for Brewster's angle for an interface between vacuum and a medium of index of refraction n. [Answer: ̸_B = tan^-1(n).]

Consider a magnetic dielectric with a permeability such that $\mu / \mu_{0}=\varepsilon / \varepsilon_{0}$. Show that for such a material the reflection coefficient for normal incidence is identically equal to zero. This realization is equivalent to the situation where the impedance is matched at the junction of two transmission line.
