Assume that a microwave oven operates at a frequency of 1.00 * 10^11

Assume that a microwave oven operates at a frequency of 1.00 * 10^11 s^-1

a)what is the wavelength of this radiation in nm?

my attempt:
wavelength=c/v so 3.00 * 10 ^8/1.00 * 10^11 s^-1= 3 * 10^19m
I would have to convert to nm correct?
so 3 * 10^19 (1 * 10^-9)= 3 * 10^10 nm??

I know it's supposed to be 3 * 10^28 nm, what am I doing wrong??

Try doing that calculation again, it looks like you did not divide the numbers properly.

Yes.

That answer is incorrect as well.

Is your calculation correct ?

Please check again.

Please check again.

3 * 10^-3? m

3 * 10^-3? m

Correct, you just need to convert that to nm.
