Homework Answers
A) A wave incident ina boundary at a critical angle can be associated with fiber optics.
Explanation: The critical angle is an angle at which the total internal reflection occurs. the total internal reflection is an important phenomenon in fiber optics.EX(optical fibers).
B) A wave incident ina boundary at a critical angle can be associated with polarizing angles.
polarizing angle means the angle at which the unpolarized light or other electromagnetic radiation must be incident upon a nonmetallic surface for the reflected radiation to acquire maximum plane polarization.if the polarizing angle equal to the critical angle maximum polarization can be achieved
C) A wave incident in a boundary at a critical angle can be associated with photography.
The critical angle is used in photography to control the light incident on the lens.
D)A wave incident in a boundary at a critical angle can be associated with filters.
The critical angle concept is used in designing the light spatial filters.

Some biological systems can act like an optical fiber. Below is a drawing which illustrates how this might occur. Imagine you have a long, thin cell surrounded by fluid with index of refraction 1.38. The average index of refraction inside the cell is 1.48. Compute the critical angle, theta_crit, for total internal reflection for this system. Show all of your computations. What will the angle of refraction be for ray A (shown below) that has an angle of incidence of...
