Answer :
Final answer:
A 101 MHz radio wave corresponds to 101,000,000 cycles or vibrations per second, with par option 'B' being the correct answer.
Explanation:
A 101 MHz radio wave has a frequency of 101,000,000 Hz or vibrations per second, since the unit MHz stands for MegaHertz, and Mega denotes million (or 1,000,000). Thus, the correct answer is (B) 101,000,000. The frequency of a radio wave tells you how many cycles of the wave pass a certain point per second. Therefore a frequency of 101 MHz means that 101,000,000 complete waves, or cycles, pass by a given point every second.
