What is the wavelength of a wave that has a speed of 30 m/s and a frequency of 6.0 hz? What is the highest frequency (shortest wavelength) that could be emitted from a TV tube which has an accelerating voltage of 2,000 volts? What is the nature of this radiatio...
The obtained upper limits around the peak of the emission at lower frequency were at a flux level 10 times higher than the observed X-ray flux (Figure 9, top panel). Figure 9. VHE observations of GRB 170817A. Top: the H.E.S.S. 1–10 TeV energy flux upper limits (green arrows) ...
