Researchers are trying to use radiocarbon dating to determine when the wooden buildings at an archaeological site were constructed. They know that trees in the area would have been cut down for the construction, and that when the trees died, they would have a ratio of carbon-14 to carbon-12 of about one part per trillion (1 ppt). The half-life for the decay of carbon-14 is 5,730 years, and they discover the ratio of carbon-14 to carbon-12 to be about 0.125 parts per trillion (ppt). What is the age of the buildings at the site? * 716.25 years

5,730 years

17,190 years

0.125 billion years

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
