A microwave oven operates at a frequency of 2.45 GHz. Calculate the wavelength of the microwaves produced.
Remember to convert frequency into hertz when using \\( c = f \\times \\lambda \\).
Microwaves are used in dual-frequency radar for measuring speed. Discuss how the different speeds of microwaves would impact the accuracy of measurements.
Consider the importance of wave patterns and their interaction with moving objects.
