11. a 6.0‐m wire with a mass of 50 g, is under tension. a transverse wave, for which the frequency is 810 hz, the wavelength is 0.40 m, and the amplitude is 4.0 mm, is propagating on the wire. the time for a crest of this wave to travel the length of the wire is closest to a) 19 ms b) 16 ms c) 21 ms d) 23 ms e) 25 ms

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?
