Parallel light from a distant object strikes the large mirror in the figure and is reflected by the small mirror that is 2.528 m from the large mirror and is actually spherical in curvature not planar as shown. The large mirror has a radius of curvature of 7.90 m. The light reflected from the second mirror is focused at a small hole at the vertex of the first (larger) mirror. What is the distance from the large mirror to the image that it produces, which becomes the object for the second mirror? What is the radius of curvature of the smaller mirror?
At what driving frequency fd do two phasors have the same length? At that driving frequency, what are (c) the phase angle in degrees, (d) the angular speed at which the phasors rotate, and (e) the current amplitude?
A friend of yours is loudly singing a single note at 410 Hz when racing toward you at 26.1 m/s on a day when the speed of sound is 339 m/s. What frequency does your friend hear if you suddenly start singing at 410 Hz.
A 125 g wire is held under a tension of 218 N with one end at x = 0 and the other at x = 12.0 m. At time t = 0, pulse 1 is sent along the wire from the end at x = 12.0 m. At time t = 25.5 ms, pulse 2 is sent along the wire from the end at x = 0. A..
