| Regarding HW#8:
Question 1:
a. Ask yourselves: How is the fact that the wavelength
is shifted from the blue end of the spectrum a little towards the red related
to its speed?
b. Use the answer from a. and the HUBBLE LAW
to find the distance.
c. Use the answer from b. and the luminosity
of 100 billion suns + our usual "trick" of finding the flux from luminosity
here.
