AI Thread Summary
The discussion revolves around the light spectrum capture capabilities of a 408mm Cassegrain telescope equipped with a CCD sensor. Key questions include determining the range of wavelengths that can be imaged on the CCD, the specific wavelength range per pixel, and the spectrograph's resolution related to the radial velocity of a radiation source centered at 600nm. Participants emphasize the importance of demonstrating problem-solving attempts, suggesting that visual aids like diagrams may facilitate understanding. The conversation highlights the need for basic geometry and optics knowledge to address these questions effectively.

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...

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
