A microwave oven operates at 2.30 GHz . What is the wavelength of the radiation produced by this appliance? Express the wavelength numerically in nanometers.
1. In the magnetotron of a microwave oven, the microwaves are produced by having electrons orbit in a magnetic field. (When the electrons do this, they emit electromagnetic waves which we will study in a few weeks). Calculate the strength of the magnetic field that causes electrons to orbit with a frequency of 2.4 GHz
