What is meant by the quality (or timbre) of sound? On what factor does the quality (or timbre) of a sound depend?
A sound wave has a time period of $0.5\ s$. What is the frequency of the sound?
Write the characteristic of the sound that describes how the brain interprets the frequency of sound is called.
Order to reduce the loudness of a sound, we have to$(a)$. decrease its frequency of vibration of the sound$(b)$. increase its frequency of vibration of the sound$(c)$. decrease its amplitude of vibration of the sound$(d)$. increase its amplitude of vibration of the sound
How the term pitch is equivalent to the frequency of sound?
Establish the relationship between speed of sound, its wavelength and frequency. If velocity of sound in air is $340\ ms^{-1}$, calculate$(i)$. wavelength when frequency is $256\ Hz$.$(ii)$. frequency when wavelength is $0.85\ m$.
Fill in the blanks : The Greater the amplitude of the vibration, the _____ is the distance a sound will travel before dying out
(a) What is meant by the ‘loudness’ of sound? On what factor does the loudness of a sound depend?(b) Draw labelled diagrams to represent (a) soft sound, and (b) loud sound, of the same frequency.
Sound Vibration Propagation of Sound
Fill in the blanks with suitable words.$(a)$. Time taken by an object to complete one oscillation is called______.$(b)$. Loudness is determined by the ________ of vibration.$(c)$. The unit of frequency is _________.$(d)$. Unwanted sound is called _________.$(e)$. The shrillness of a sound is determined by the _________ of vibration.
Define amplitude, time period, and frequency of sound wave.
How is the sound produced? What are the three properties of sound?
(a) Name four ways in which sound can be produced.(b) Calculate the speed of a sound wave whose frequency is 2 kHz and wavelength 65 cm.
