any help?

I know there are many ways to identify the spectra but, what are the advantages and disadvantages of using the first and second order lines to identify spectra? Please Help! If u don't want give me answer then suggest me some links. Thanks

thanks! another quick question I know tht ultraviolet and ifrared are not visible to human eyes, but where would it be appear on spectrometer?

is fluoracent lamp could be use of this method?

actually this is a lab. we used spectrometer for to find Hydrogen and Helium wavelengths at some colors

we are learning about The Grating Spectrometer

We all don't have any clue about this, since he did not went over it.

Try this if ur given values 768.8J and 26.96 are right: • Charge remaining after t s., Q = CV e^ -[1/CR]t • Energy lost = 768 – Q^2 / 2C

any attempts?

the answer was positive Thanks for all Help guys!

yes, I thought it would be "Cooking with Gas", but i was not sure thts why i hv asked

The spectrum tubes work by runnig an electric current through a sealed tube containing gas. What common use of this method can you think of?

is it suppose to be positve b/c M =absolute[h(image)/h(object)] or is it neg.?

any help? please
