Question

What is the frequency of an electromagnetic wave that has a wavelength of `3.7 times 10^-11` `m` in a vacuum?

Answer 1

Well, `c=nuxxlambda`

Explanation:

This question could have been asked in the physics section, mind you chemists regularly work with wave phenomena.

We want `nu=(c("the speed of light"))/(lambda("wavelength"))`

And so we plug in the numbers to the given quotient:

`(3xx10^8*m*s^-1)/(3.7xx10^-11*m)=8.11xx10^(18)*s^-1`.

This frequency is in X-ray region............
