How Does a 408mm Cassegrain Telescope's CCD Capture Light Spectrum?

[rubble]

hey guys anyone got any ideas on this:

f/19 cassegrain focus of a 408mm telescope. ccd is 12.3mm long, each pixel is a square of side 24 x 10E-6 m, grating used has 1200lines/mm

1. = the spectrum is imaged on a ccd with a zoo lens such that the dispersion is 3.3nm/mm. what is the range of wavelengths that can be imaged on the ccd?

2. = the range of wavelengths that fall on a single ccd pixel

3. = the resolution of this spectrograph in terms of the radial velocity of the source of radiation, if the spectrum is centred on 600nm

cheers everyone!

You will have to show your attempt at a solution before anybody can help you.

Have you drawn a picture? It's mostly high-school geometry...
