12 Questions
What does wavelength represent in the context of waves?
The distance between two consecutive crests or troughs
How is frequency of a sound wave defined?
The number of oscillations made by a particle in one second
What is the SI unit of wavelength?
Metre
Which of the following best describes amplitude?
Maximum displacement of a particle from its mean position
What is the time period of an oscillation?
Time taken to complete one oscillation
What is the main difference between monophonic music and polyphonic music?
Monophonic music is composed in simple tones, while polyphonic music is a mixture of pure tones played together.
What type of sound is described as monotone?
'A tone with pressure variation described by a single frequency
What characterizes the intensity or loudness of sound?
The loudness of sound is the degree of sensation produced in the ear, while intensity is the amount of vibrational energy per unit area per second.
How does pitch or shrillness relate to frequency in sound?
High pitch corresponds to high frequency, while low pitch corresponds to low frequency.
What defines quality or timbre of a sound?
Quality or timbre distinguishes between sounds even if they have the same intensity and pitch.
How is intensity related to loudness in pure tones with increasing frequency?
Loudness increases with increasing frequency, but intensity decreases with increasing frequency.
What distinguishes monophonic music from polyphonic music in terms of composition?
Polyphonic music involves a mixture of pure tones played together, while monophonic music contains simple tones.
