Question

What is the wavelength of electromagnetic radiation having a frequency of `5.00*10^12` `s`?

Answer 1

We use the relationship `c=nuxxlambda`

Explanation:

And thus `lambda=c/nu=(3.00xx10^8*ms^-1)/(5.00xx10^12*s^-1)=6.00xx10^-5*m`.,,,,,,,,,,,

............... which I think is in the `"IR"` region..........
