The production of sound happens in different ways. Some of them are listed below:
For example, when a rubber band is plucked, it creates a vibration, resulting in the production of sound.
Also, when a tuning fork is struck to a rubber pad, it vibrates, creating a sonorous sound.
After understanding what sound is and how it is produced, the next concept we need to understand is the propagation of sound.
Reflection of light occurs as the waves encounter a reflecting surface or its borders, not absorbing the radiation energy while the waves bounce back from the body. When light rays reflect a body, they travel from one transparent medium to another or move through a medium with a frequently altered composition. According to the law of reflection:
Till now, you would have understood that sound is a wave formed due to a disturbance in the particles. Now, we need to get a better understanding of sound as a longitudinal wave and the types of waves.
Based on the direction of propagation, a wave can be categorised into two types—transverse and longitudinal waves.
Here are a few characteristics of sound waves:
This is a crucial chapter for students because there are several concepts that students have to use even in their college. The chapter holds a good score in JEE and other competitive examinations. Students who wish to take science as their stream in Class 11th should concentrate well on this chapter and learn all the fundamentals.
