Question

A microwave oven operates at 2.40 GHz. What is the wavelength of the radiation produced by this appliance?

I got 1.25*10^-10.

What am I doing wrong?

Answer 1

Is the speed of light 3 x 10^8 m/s?
Is 2.5 GHz 2.5 x 10^9 Hz?
Does 0.125 m wavelength sound better?

Answer 2

oh my! thank you, conversion factors off i guess :[
