A continuous traveling wave with amplitude A is incident on a boundary.The continuous reflection, with a smaller amplitude B, travels back through the incoming wave.The resulting interference pattern is displayed in thr figure. The standing wave ratio is defined to be A+B SWR=2 A-B The reflection coefficient Ris the ratio of the power of the reflected wave to the power of the incoming wave and is thus proportional to the ratio (B/A)2. What is the SWR for (a) total reflection...

Consider a vertically incoming (incident) P-wave striking a
horizontally stratified earth (Fig. 2). The amplitude of the
transmitted P-wave at the top boundary of layer 1 is 1 (don’t worry
about units for amplitude). What is the amplitude of the P-wave
reflected from the boundary between layers 3 and 4? What is the
amplitude of the P-wave transmitted into layer 4? What are the
amplitudes of the corresponding S-waves? Express amplitudes in
relative terms (relative to the amplitude of the...

Adjacent antinodes of a standing wave of a string are 20.0 cm apart. A particle at an antinode oscillates in simple harmonic motion with amplitude 0.600 cm and period 0.100 s. The string lies along the +x-axis and its left end is fixed at x = 0. The string is 70.0 cm long. At time t = 0, the first antinode is at maximum positive displacement. a. Is the right end of the string fixed or free? Explain. b. Sketch...
