Description
The Third unit of the Advanced Level Physics subject, the first part of the Oscillations & Waves Lesson, the Oscillations section, is explained in detail in this book.
This book has been written by Dr. P. Geekianage.
This book has been explained under the following sub-topics.
- Introduction to Oscillations and Waves
- Oscillations
- Simple Harmonic Motion
- Relationship between simple harmonic motion and circular motion
- Velocity of a body executing simple harmonic motion
- Acceleration of a body executing simple harmonic motion
- Phase difference of two oscillations
- Energy stored in a body executing simple harmonic motion
- Energy transformations
- Study of oscillations of a simple pendulum
- Determination of the acceleration due to gravity using the simple pendulum
- Study of oscillations of a helical spring hung vertically
- Determination of a spring constant of a spring by oscillation method
- Study of oscillations of a body floating in a liquid
- Free Oscillations
- Damped Oscillations
- Forced Oscillations
- Demonstration of forced oscillations using Barton’s Pendulums
- Natural and Artificial frequencies of an oscillating object
- Resonance
- Demonstration of mechanical resonance using Barton’s Pendulums
- Examples of instances of resonance
- Exercise 1
- Exercise 2
Since the theories have been explained well, you can study and understand them on your own.
Since exercises are also given, it will be easy for you to study.
