A firefighter stands on the ladder of a fire truck. To fight a fire in a tall building he needs a water speed of at least 5.00 m/s as the water leaves the hose. The water is taken from the city water main which is located 4.00 m below ground, where the water pressure is kept at a constant pressure of 6.013 x 10° Pa. If the hose and water main have diameters of 2.00 cm and 20.00 cm, respectively, find: a.) How fast (in m/s) is the water in the main moving once the hose is in use? b.) What is the maximum height (in m) to which the firefighter can climb to fight the fire?

6.2-5 Refraction at the Brewster Angle. Use the condition n1 sec 01 = n2 sec 02 and Snell's law, n, sin 61 = n2 sin 62, to derive (6.2-12) for the Brewster angle. Also show that at the Brewster angle, 0 + 02 = 90°, so that the directions of the reflected and refracted waves are orthogonal, and hence the electric field of the refracted TM wave is parallel to the direction of the reflected wave. The reflection of light may be regarded as a scattering process in which the refracted wave acts as a source of radiation generating the reflected wave. At the Brewster angle, this source oscillates in a direction parallel to the direction of propagation of the reflected wave, so that radiation cannot occur and no TM light is reflected.
