Answer #1

Initially, the power circle maintains to have an expanding radius, so the entire electricity is shipped flippantly along that circumference. As the circumference grows, the electricity per unit length reduced. The power is seen thru the amplitude of the wave, so as the electricity in line with unit length decreases, so does the amplitude.

Secondly the lower is because of losses of power by using the tour of the wave through the medium. Friction and other non-conservative forces will act to do away with the wave electricity and transform it into other kinds.

In three to five sentences, explain why two slightly separated coherent sources of circular waves results in an alternating pattern of “bright” and “dark” bands on a screen held some reasonable distance away. Assume the two sources are coherently in phase (e.g., both are at a peak at a particular instant) at the same frequency.

Diffraction occurs for all types of waves, including sound waves. High-frequency sound from a distant source with wavelength 8.70 cm passes through a narrow slit 12.5 cm wide. A microphone is placed 45.0 cm directly in front of the center of the slit, corresponding to point O in the figure 36.5a in the textbook. The microphone is then moved in a direction perpendicular to the line from the center of the slit to point O.At what minimal distance from O...

Suppose water is leaking from a tank through a circular hole of area Ah at its bottom. When water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cAh 2gh , where c (0 < c < 1) is an empirical constant. A tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its...
