Calculate wavelength to frequency

[dervast]

Hi i am trying to calculate what is the frequency of the 600nm that our eye can see...
I am calculating the
f=(c/l)
(3*10^8)/(600*10^-9)=0.5*10^19 whics means 5phZ... Is it coreect?

I have tried to calculate using MATLAB but the results don't agree
>> (3*10^8)/(600*10-9)

ans =

5.0075e+004

I think you meant 0.5Phz or 500Thz, which is correct.

thx a lot

(3*10^8)/(600*10-9)
(3*10^8)/(6*10-7)=0.5*10^15=500Thz and u are right

How can u understand the matlabs ouput?
5.0075e+004

 

[Pengwuino]

e+004 means E04 which is basically 5.0075 * 10^4

I think you screwed up when you entered: (3*10^8)/(600*10-9)

The program probably did 600 * 10 * -9 or something because you didn't enter it in correctly.

>> (3*10^8)/(600*10^-9)

ans =

5.0000e+014

thx
