question 2
An astronomer measures the wavelength of an absorption line in the
spectrum of light from a galaxy to be 720.6 nm.
If the true wavelength of the spectral line is 654.8 nm, calculate the
radial velocity of the galaxy.

It should be 2807 dots.

And that was under two minutes. I'll let someone else take question 2 :P

I got 2807 too, but I cheated: I just counted the number of dots in the longest row, used a calculator to add consecutively, multiplied, and subtracted the one - no maths for me thankyou.
