The electromagnetic waves used in a microwave oven have a wavelength of 12.24 cm.
(a) What is the frequency of this radiation?
(b) Electromagnetic waves in a microwave can exhibit standing waves. If there is a standing wave in your microwave oven, what is the distance between nodes? (Assume these are standing waves in one dimension; i.e., as in a wave on a string.)
(c) Based on your answer in part (b), why do you think microwave ovens contain rotating carousels?
