Figure 2 shows observations of the spectrum of another star, like the Sun but more distant, as seen from the Earth over the course of a year. The wavelength range shown is the same tiny portion of the spectrum shown in the bottom panel of the earlier figure, and the same two prominent iron lines are seen. From laboratory measurements of such atoms, it is known that the wavelengths of these two lines are hemit - 633.53 for the shorter...

Number three please
The temperature of a student's skin is 33.0 degree C. At what wavelength does the radiation emitted from the skin reach its peak? The radius of our Sun is 6.96 times 10^8 m, and its total power output is 3.85 times 10^26 W. (a) Assuming the Sun's surface emits as a black body, calculate its surface temperature. (b) Using the result of part (a), find lambda_max for the Sun. Calculate the energy in electron volts of a...

A small coastal town in Queensland is subject to an increasing permanent population and also a transient influx of tourists during the summer period. Council already receives frequent complaints of restricted water supply. The water supply system comprises a rising trunk main from the treatment plant A to the service reservoir B, the service reservoir, and service mains to the consumption areas. Two consumption areas C and D at different elevations are gravity supplied from the service reservoir. The service...
