Ok, here's the problem (and I might post more later on)...
Determine the frequency of light with a wavelength of 0.000047 cm.
Any help will be appreciated.

Would I do V=Wavelength over Plancks constant? Owell I'm goin for it.

V=c/W
V is frequency
c is the speed of light
W is the wavelength
remember to convert the wavelength to nanometers to give a final unit of hertz.

i can't believe ima do this...
speed of light is 3 x 10*8 m/s
wavelength is .00000047m
devide .00000047 by 300000000 and you get your answer
its physics btw

Ok here's another one, ahem.
How are frequency and wavelength related in electromagnetic radiation?
and heres another...
Two compounds have the same empirical formula, must they have the same molecular formula? give an example.

haha, yeah. I took AP and had the worst teacher. She literaly just told us to read the book and take notes, and never actualy explained anything. Not to mention i had no idea what half the AP test was about.

frequency and wavelength are inversely proportional to each other. the smaller the wavelength, the greater the frequency.
c=v*lambda, so divide c (which is 3 * 10^8 m/s by your wavelength (in meters), so that your units will end up to be 1/s, which is the same as a Hz (Hertz). i believe your unit was in cm, so divide it by 100 to get it into meters)
molecular formula and empirical formula dont have to be the same. empirical formula just gives the ratio of your elements, not the actual proportions. that is the molecular formula. for example, for empirical formula C3 H6 O3, the molecular formula can be that of pyruvate where its the same, or that of glucose C6 H12 O6.
and to the guy that said that this is physics, radiation can be treated from both a chemical and physical point of view.

sry i suck at chemistry. we're doing redox reactions now i havent learned anything about wavelengths or whatever.

remeber OIL RIG (oxidation is loss of electrons, Reduction is gain of electrons) the rest is just adding water and acid/base

Heres another,
What mass of silver will be produced when 65 g of copper reacts with an excess of silver nitrate? (507.6g)
and
How do you distinguish between an ionic, polar covalent and nonpolar covalent bond (pretty sure it has to do with electronegativity)

This is retarded. Dont you have a class discussion board dedicated for this? And us giving you the answers wont help you when it comes to a test. Take my advice, just sit down and learn how to do it. It'll benefit you in the long run.

When I'm trying to finish the problems I have no clue how to do, when it's due tomorrow, I don't have time to re-learn it. This packet counts as 50% of our final exam so as long as I finish this I can get a 40% on the actual test (which is multiple choice) and have a passing grade. I'm mostly done now, thanks to everybody that helped.

This year I'm in Chem 1 Honors.
Next year I'll have Chem 2 AP. I'll be 16.
All times are Eastern (-4)
