There's no way to predict that..Here's what I'm thinking is right:
1/pi = R(1/nf - 1/ni)
R = 109737 cm
nf = 750 nm = 7.5*10^-5 CM
ni = 490 nm = 4.9*10^10-9 CM
So...
1/pi = 109737 (1/(7.5*10^-5) - 1/(4.9*10^-9)) =
1/pi = -2.23*10^13
UGHhhh...what the heck! I JUST DONT GET...
Bump.
I've figured everything out. But can't still solve this question:
"Using the Rhydberg equation, calculate the transitions in the H-atom that are taking place to give rise to each line."
If you look at my data, it has 7 lines...Shouldn't I just be calculating it from the highest line I...
Homework Statement
I'm just curious to if I have answered this questions properly, and was wondering if someone can see if I should add more to what I have written, or completely change my answer. I'm pretty confident with what I've answered, but would like someone to check :)
So to begin...
1. Convert 1.2 in^2 to cm^2
2. 1 CM = 10^-2 and 1 inch = 2.54 centimeteres
The Attempt at a Solution
Can't we just do 1.2*2.54=3.048 and write that as our answer?
For the following data set of eight values, give the MEAN, DEVIATION (DEV), and AVERAGE DEVIATION (AD). Show a sample calculation for each: 0.77, 0.92, 1.12, 1.00, 0.96, 0.88, 1.16, 1.02
Homework Equations
Well before we began, can anyone take the courtesy and see if I'm getting the...
Thanks, I was right :) I even asked the teacher, he confirmed it. Also, there's this odd question...
"What does it mean when you a piece of glassware that is "graduated" or has "graduations" on it?" Couldn't we describe graduations as precise measuring marks?
I'm curious if I'm doing this chemistry lab correctly or not. If you open the link below, you can see the lab. Basically, my job right now is to write a well formulated procedure on how to perform this lab.
So, for this lab, am I supposed to be calculating the mass of the substance (h2o in...
Hello, all. I'm doing a review in the back of my Calculus book and need help on this particular problem. The book has the answer, but I don't understand how to get it. If someone can show me steps to solving this problem, it would be greatly appreciated.
Problem: The distance a person can walk...
Homework Statement
Assume that Earth’s magnetic field is everywhere perpendicular to the path of a proton
and that Earth’s magnetic field has an intensity of 4.07 × 10−8 T.
What speed would a proton need to achieve
in order to circle Earth 1660.0 km above the
magnetic equator?
Answer...
:o, thanks a ton man. I think this was a trick question...Since I never thought of the diameter. It makes sense why its 26.7-18 instead of 9.
Thanks for clearing it up, I was really starting to get a little confused there.
