Microwave ovens operate at a frequency of very close to 254

Microwave ovens operate at a frequency of very close to 2.54 GHz. Use this to determine the wavelength of your wave. Make a sketch, with explanation and scale showing what the electric field will look like as a function of space at several different times (e.g. t=0, t=0.25, t=0.5, t=0.75, and t=) in the oven.

I got (1.181 * 10^8 nm) but i dont know how to graph this

Solution

wavelength = speed/frequency = 3x 10^8/(2.54 x 10^9)= 0.118 m

that means t=0 to t= pi, on scale graph paper distance should be 0.118/2=0.059 m
