Dear Students,

In Ch#11-Sound, we will study about the explanation of production of sound waves, describe the longitudinal nature of sound waves, define the terms pitch, loudness and quality of sound, describe the effect of change in amplitude on loudness and the effect of change in frequency on pitch of sound, define intensity and state its SI unit, describe intensity level and mention its unit, describe the importance of acoustic protection, describe that noise is a nuisance, describe how reflection of sound may produce echo, describe audible frequency range and describe the uses of ultrasound. The Numerical Problems against this chapter are given below:
