If the flux density of bremsstrahlung from an optically thin source is 9.7 x 1015 W m2 and the frequency for the region of the spectrum is ν > 1012 Hz, sketch a log-log graph of flux density against frequency for this region.

The monochromatic flux of the Crab pulsar has a frequency dependence of Fν∝ν^−0.3 between 10^10Hz and 10^12Hz. What is the slope of a graph of log Fλ against log λ ? At which wavelength would you expect the flux to peak? The monochromatic flux of a radio source has a frequency dependence of F, a v-2.5 when measured in frequency units. What is the slope of a graph of log Fi against log \? At which end of the electromagnetic...
