Question
Which of the following determines the loudness or
softness of the sound?Solution
Sound : The sound is a longitudinal wave in which the particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. Loudness : The phenomenon of sound waves that depend on the amplitude and energy of the sound wave is called Loudness. • When the amplitude of the sound is large, then the sound wave is considered to be loud. Frequency: The number of wave cycles happening per second is called frequency. Amplitude : The maximum amount of displacement of the medium particles from its mean position is called the amplitude of the wave. Wavelength : The distance between two adjacent maxima or two adjacent minima of a wave is called wavelength of that wave. It is denoted by λ. Pitch : The response of the ear to the frequency of sound is called the pitch of the sound.
