Any motion which repeats itself at regular intervals of time is known as periodic motion. If a body moves back and forth repeatedly about its mean position then it is said to be in oscillatory motion.
For example: The to and fro movement of pendulum and a child swinging on a swing.
Oscillations can also be defined as periodic to and fro motion which repeats itself at regular intervals of time.
In Class 11 Physics NCERT chapter 14, Oscillations; oscillatory motion, its different types, laws governing this motion and other related facts are explained in lucid manner. This chapter also includes some unsolved questions and solved examples which give an idea about what type of questions can be framed on the basis of the topics discussed in the chapter. Solved examples give an idea about how to frame appropriate answers to other questions of similar type.
In this article we are providing NCERT Solutions for Class 11 Physics chapter 14- Oscillations. These solutions have been framed keeping the students' perspective in mind and will help the students with easy and simple understanding of the concept and technique employed in solving all the NCERT questions.
