1. Why do optical fibers have a minimum bend radius? What might happen if this minimum bend radius is exceeded?
2. Find or create your own application for the color dependence of the index of refraction. Your example need not be fully developed, but it should (1) address some task, and (2) be clear about the application of the color dependence to the task.
An air parcel occupied by an ideal gas (T1 = 255 K, V1 = 1500 m3, m1 = 1680 kg) collides and mixes with a second air parcel occupied by a second ideal gas (T2 = 280 K, V2 = 1200m3, m2 = 1392 kg). Assuming the specific heat capacities of the gases in ..
