I recently did a chemistry lab where you use a handheld spectrometer and had to look at the sun, a fluorescent light, H lamp,He lamp, Kr lamp, Ne lamp and a Xe lamp. We also did flame test of some solutions and where supposed to look through a cobalt glass with the spectrometer and record the...
...figure out why my answer's wrong? wavelength = h / mu, right?
h = 6.63*10^-34
mass of an electron (m) = 9.10938188 × 10^-31
velocity (u) = 1.03*10^5
(6.63*10^-34) / (9.10938188 × 10^-31)*(1.03*10^5)
= 74.99
so why does my answer come up wrong? any help at all would be appreciated. i'm lost...
cm which travel at 343 m/s through air? When a tuning fork is struck, it produces sound waves of wavelength 114 cm which travel at 343 m/s through air?
In general, the speed of sound depends on the state and temperature of the medium such that:

I know this question is relatively straight forward, but when i try to submit the answer, the program I'm using keeps telling me it's incorrect. I used the formula Lambda = h/mv :
(6.62600 * (10^(-34))) / ((9.10900 * (10^(-31))) * (1.14 * (10^5))) = 6.38081096 × 10-9
Can someone pleeease tell...
Electron transition that is. I am thinking the further the "jump", the higher the energy and hence the shorter wavelength, so n4 to n1 has the shortest wavelength, and n4 to n3 has the longest wavelength! Am I thinking right?

...a radio wave from an AM stati? station* broadcasting at a frequency of 750kHz? Find the frequency in m and km and compare it to some familiar object of similar length.
I don't understand the question... I don't understand how to solve it. And I really don't know what you meant by that...
