WebThe shrillness of a sound is determined by th e frequency of vibration. The characteristics of sound which depend on frequency are called the pitch of a sound or shrillness of the sound. If the frequency is high, the sound is shrill and has a higher pitch. WebMar 25, 2024 · Loudness of a sound depends on the intensity that the sound has produced. Which depends on the amplitude or the energy with which sound has been produced. …

WebApr 2, 2024 · Think whether the shrillness or pitch depends on wavelength, frequency or amplitude i.e. loudness of the voice. Complete step-by-step solution - When a singer sings, we say that at some part the pitch is low or at some part the pitch is higher. Actually, what we are talking about is the frequency of the sound in the song. WebThe quantity on which the pitch of sound depends, is called frequency. Frequency is no. of oscillations made by each particle in the medium when sound propagates through it. Its S.I. unit is per second (s − 1) or hertz (Hz). 1 s − 1 = 1 Hz our state government
Sound Class 9 Notes, Science Chapter 12 Explanation
WebMar 30, 2024 · Suppose if vibration of sound is 50 vibrations per second, it means its frequency is 50 hz Note - Frequency determines shrillness or pitch of sound More the frequency, more the shrillness of sound Less the frequency, less the shrillness of sound Example 1 Voice of Baby is of high pitch Voice of grown up man is low pitch Example 2 WebThe loudness of sound is measured in Decibel (db). If loudness exceeds 80 db, then the sound becomes physically painful. Pitch The pitch of sound depends on its frequency. If … WebQ. How does the pitch of the sound depend on frequency? Q. Write true or false for each statement: (a) When sound propagates in air,it does not carry energy with it. (b) In a longitudinal wave,compression and rarefaction are formed. (c) The distance from one compression to nearest rarefaction is called wavelength. our state magazine ed fitts
