A microwave oven uses microwaves with a frequency of 2.45 GHz (gigahertz) to heat food. Microwaves within the oven are reflected by the walls and can produce a standing wave pattern, in which hot spots are found at the antinodes and cold spots at the nodes. If there is no turntable to rotate the food and ensure even cooking, this can produce burn marks at anti-node positions. What separation distance do you expect between consecutive burn marks? Give your answer in cm.
