Hello guys,

I'm doing a comparison between Planck's, Rayleigh's and Wien's formula, and I'm plotting the following function in mathematica

Plot[{(2 h (v 10^11)^3)/c^2 10^17/(Exp[(h (v 10^11))/(k T)] - 1), (
2 (v 10^11)^2)/c^2 k T 10^17, (2 h (v 10^11)^3)/
c^2 Exp[-((h (v 10^11))/(k T))] 10^17}, {v, 0 10^0,
5}, {PlotRange -> 2 10^0, PlotStyle -> Thick,
AxesLabel -> {Frequency (10^11 Hz),
Energy/surface\[Cross]time (10^-17 J/(m^2 s))}}]

If you plot this, you'll see that the label is written as 100000000000 Hz.

Can anyone tell me please how to write it as 10^11?

Thanks

You can write text as "text" and Mathematica will plot exactly what you wrote (but will no longer interpret it as mathematics). You can find info like this in the Documentation Center built into Mathematica for every command (e.g., AxesLabel).

I tried text, but it's still taking it as a number! I don't understand why!!!! :(

Are you enclosing 10^11 in quotation marks? Works for me.
