A 15 GHz signal is injected into a vacuum-filled, copper Ku-band waveguide. The waveguide is connected to another Ku-Band waveguide, but this one is filled with polyethylene (assume semi-infinite waveguides). Design a quarter-wavelength matching section to eliminate reflections from this configuration. Draw a picture of the system (the three waveguide sections) and label all relevant dimensions and values.

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?

Tsunamis are fast-moving waves often generated by underwater earthquakes. in the deep ocean their amplitude is barely noticeable, but upon reaching shore they can rise to an astonishing height of a six-story building. one tsunami generated off the aleutian islands in alaska, had a wavelength of 897km and traveled a distance of 3280km in 4.18h. (a) what was the speed (in m/s) of the wave? find the waves (b) frequency and (c) period.
