Answer:
Wavelength = 0.15 m
Step-by-step explanation:
The frequency of a microwave oven is 2.00 GHz or
.
We need to find the wavelength of the radiation produced by this appliance. We know that the relationship between the frequency and wavelength is given by :

Where,
is the wavelength
So,

So, the wavelength of the radiation produced by this appliance is 0.15 m.
