Calculate wavelength to frequency

In summary, the conversation was about calculating the frequency of light at 600nm and the results obtained using MATLAB. The correct frequency is 500Thz, but there was some confusion with the input which resulted in a different output.

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

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

What is the formula for calculating wavelength to frequency?

The formula for calculating wavelength (λ) to frequency (f) is: f = c/λ, where c is the speed of light (3.00 x 10^8 m/s).

How do I convert a given wavelength to frequency?

To convert a given wavelength to frequency, use the formula f = c/λ, where c is the speed of light. Simply plug in the wavelength value in meters to the formula and solve for frequency in hertz (Hz).

What units are used for wavelength and frequency?

Wavelength is typically measured in meters (m), while frequency is measured in hertz (Hz). However, other units such as nanometers (nm) or megahertz (MHz) may also be used depending on the context.

Is there a relationship between wavelength and frequency?

Yes, there is an inverse relationship between wavelength and frequency. As wavelength increases, frequency decreases, and vice versa. This is known as the wavelength-frequency relationship.

Can I use the same formula to calculate frequency to wavelength?

Yes, the same formula f = c/λ can be used to calculate frequency to wavelength. Simply rearrange the formula to solve for wavelength (λ) instead of frequency (f).
