Final answer:
The type of electromagnetic wave with a wavelength similar to a PBA basketball court (28 meters) is a radio wave.
Step-by-step explanation:
The question asks about an electromagnetic (EM) wave type with a wavelength comparable to the size of a PBA basketball court, which is 28 meters. The options provided include microwaves, radio waves, ultraviolet, and visible light. Among these, the correct type of EM wave that can have a wavelength similar to 28 meters is a radio wave. Microwave radiation typically has wavelengths ranging from 1 millimeter to 1 meter, making it too short. Both ultraviolet and visible light have much shorter wavelengths than a basketball court. Radio waves, on the other hand, cover a broad range of wavelengths from about 1 millimeter (mm) to several kilometers (km), placing them on the low-frequency end of the electromagnetic spectrum. Therefore, a radio wave can indeed have a wavelength as large as 28 meters, matching the size of a PBA basketball court.
