How many oscillations per second does an object make if it has a frequ...
Understanding Frequency
Frequency is a key concept in physics that refers to the number of oscillations or cycles an object completes in one second. It is measured in hertz (Hz), where 1 Hz equals 1 cycle per second.
Given Information
- The problem states that an object has a frequency of 20 Hz.
Calculating Oscillations
- Frequency directly indicates how many oscillations occur in one second:
- If the frequency is 20 Hz, this means the object completes 20 oscillations every second.
Options Analysis
- Let’s evaluate the options:
- a) 1 oscillation per second
- b) 10 oscillations per second
- c) 20 oscillations per second
- d) 40 oscillations per second
- The correct answer is option 'c', which states that the object makes 20 oscillations per second, aligning perfectly with the frequency provided.
Conclusion
- Therefore, when an object has a frequency of 20 Hz, it oscillates 20 times every second. This clear relationship between frequency and oscillations is fundamental in understanding wave motion and periodic phenomena in physics.
