The problem states the wave oscillates 50 times per second.
Frequency is defined as the number of oscillations per second, measured in Hertz (Hz).
Therefore, the frequency of the wave is 50 Hz.
The correct answer is 50 hertz .
Explanation
Understanding the Problem The problem states that a wave oscillates 50 times per second. We need to determine the frequency of this wave and select the correct answer from the given options.
Frequency Definition The frequency of a wave is defined as the number of oscillations per second. The unit of frequency is Hertz (Hz), where 1 Hz means 1 oscillation per second.
Determining the Frequency Since the wave oscillates 50 times per second, its frequency is 50 Hz. Now we look at the answer choices to find the one that matches 50 Hz.
Selecting the Correct Answer The correct answer is B. 50 hertz.
Examples
Understanding wave frequency is crucial in many real-world applications. For example, in telecommunications, the frequency of radio waves determines which station you are tuning into. Similarly, in music, the frequency of a sound wave determines the pitch of the sound. By understanding the relationship between oscillations and frequency, we can better understand and utilize these technologies.
The frequency of the wave oscillating 50 times per second is 50 Hertz. Therefore, the correct answer is B. 50 hertz.
