Final answer:
The frequency that fits within the typical microwave range is B) 5.00 x 10¹° Hz, equivalent to 50 GHz, which is suitable for microwave applications.
Step-by-step explanation:
The frequency of microwaves falls within a specific range of the electromagnetic spectrum, typically from about 1 GHz (10¹ Hz) to 300 GHz (10¹² Hz). The option that fits within this range is B) 5.00 x 10¹°, which is equivalent to 50 GHz and is a believable frequency for microwaves used in communication or microwave ovens.
