The solutions of the ICSE Selina publication for Class 8 covers all the questions given in the Selina Publication for class 8 in that particular chapter. The answers provided in these Solutions by BYJU’S are accurate and precise in the examination point of view.
The form of energy produced by a vibrating object is known as Sound. The to and fro motion of an object is called vibration. A material medium is required for the propagation of sound. As there is no material in the vacuum, sound cannot propagate through it.
Different components that you learn in this chapter are:
Amplitude: Maximum displacement of a vibrating particle from its mean position.
Time period: The time taken for a vibrating particle to complete one full oscillation.
Frequency: The number of vibrations per second.
Characteristics of Sound: The sound originated by any means have the following characteristics, namely, loudness, pitch or shrillness, and quality or timbre. The chapter deals with all these attributes in details
