Question

Okay so i'm totally lost :/ help plz..... I will fan and metal

Using the conversion factor from eV (electron volts) to joules, determine which energy line for an electron dropping from one energy level to another would show a line at 435 nm in an emission spectrum. Use the formulas and the energy level information below to answer the question.
Needed constants:
1.00eV=1.6*10^(-19) J
C= 3.0*10^(8) M/J
H= 6.63*10^(-34) J*S

Energy Level Values:
E6:E= -0.378eV
E5:E= -0.544eV
E4:E= -0.850eV
E3:E= -1.51eV
E2:E= -3.403V

sorry

Answer 5

idk

Answer 6

@Warriorz13

Answer 7

do u want the EXACT formula for the calculation of the wavelength? or a better approach( a bit longer) , that is more explanatory?

Answer 8

lol i have no freaking clue srry hun lmfao

Answer 9

I'm already here

Answer 10

can You type the formula and me and you work it out together ? (: @AnthonyStark

Answer 11

,,im really sorry i dont know the exact formula for this specific question,,,,but u can get it using the basics,,,

Answer 12

lets put the question in simple terms ;;;;;- this is what happens,,, an electron in some energy level (say 5th level) decides to fall back to a lower energy level (say 3rd) ,,and when this happens a photon having energy equal to the difference in energy levels of these , is given out
