Answer :
Final answer:
The number of vibrations per second associated with a 101-MHz radio wave is 101,000,000.The correct answer is option (B).
Explanation:
To determine the number of vibrations per second associated with a 101-MHz radio wave, we need to know the frequency of the wave. Here, the frequency is given as 101 MHz. To convert this frequency into vibrations per second, we can use the relationship:
Vibrations per second = Frequency (in hertz)
Since 1 MHz = 1 × 10^6 Hz, the frequency of the radio wave is 101 × 10⁶ Hz. Therefore, the number of vibrations per second would be 101,000,000 vibrations per second, which corresponds to option B) 101,000,000.
