We know that 1 meV = 8.066 cm

^{-1}. So now can i say 1 cm = 8.066 meV

^{-1}????

thanks for your reply.

Ps: 1 cm

^{-1}= 0.124 meV.

It actually is a straight-forward conversion.

Start with E=hf.

So if you have 1 eV = hf, it gives you an equivalence

1 eV == 2.4 e14 Hz

but we know that f = c/lambda.

So 1/lambda = cf = 8.05 e3/cm == 1 eV.

The list of values of the conversion from 1 eV into frequency, 1/cm, and Kelvin can be found in the inside back cover of Ashcroft and Mermin's Solid State Text.

we know

[tex]E=hc/\lambda[/tex]

and so

[tex]1/\lambda=E/(hc)[/tex]

Now by taking E = 1 eV, h in eVs and c in cm/s

one will get [tex]1/\lambda[/tex] = 8066 cm

So 1 meV = 8.066 cm

But my questions is whether the following is correct or not!!!!!???

1 cm = 8.066 meV

But my questions is whether the following is correct or not!!!!!???

1 cm = 8.066 meV^{-1}[i just reversed the units!]

Yes, but remember here that it's (meV)

just as cm

First time I worked with cm
