Question

Part A has been answered correctly and should be used to answer Part B

I Review I Constants I Periodic Table
Microwave ovens use microwave radiation to heat
food. The microwaves are absorbed by moisture in
the food, which is transferred to other components
of the food. As the water becomes hotter, so does
the food. Suppose that the microwave radiation has
a wavelength of 11.2 cm.
