vibration.
wave.
pulse.
![Check Mark](/static/check-mark.png)
Answer to Problem 1AC
Solution:
Option (b) is correct.
Explanation of Solution
Reason for the correct options:
The term vibration is used for the motion of a particle which repeats itself. Hence, a back-and-forth motion that repeats itself is termed as a vibration.
Hence, option (b) is correct.
Reason for the incorrect options:
Option (a) is incorrect because spring itself does not create back-and-forth motion. When the spring is attached with a mass at its end and can compress or stretch, then the motion it creates is back-and-forth motion about its unstretched position. So, it is a wrong answer.
Option (c) is incorrect because the wave is an example of back-and-forth motion but in this case, the movement may or may not involve matter. It does not repeat itself. So, it is a wrong answer.
Option (d) is incorrect because the pulse is a type of non-sinusoidal wave. It is a type of back-and-forth motion, but it does not repeat itself. So, it is a wrong answer.
Hence, options (a), (c) and (d) are incorrect.
Conclusion:
The vibration is a repeating back-and-forth motion.
