उत्तर
The pitch of a note determined by its frequency.
(i.e., the presence of secondary tones along with the principal note)

The lower the frequency of vibration, the higher is the pitch.
The sound from a mosquito is produced when it vibrates its wings at an average rate of 500 vibrations per second. What is the time period of the vibration?
The ratio of amplitude of two waves is 3:4. What is the ratio of their loudness?
When sound travels in form of a wave
What is longitudinal wave?
Name and define the characteristic which enables one to distinguish two sounds of same loudness, but of different frequencies, given by the same instrument.
The frequencies of notes given by flute, guitar and trumpet are respectively 400 Hz, 200 Hz and 500 Hz. Which one of these has the highest pitch?
Explain the following and illustrate your answer by drawing appropriate diagram:
Frequency
A 0.6 m long stretched wire is made to vibrate in two different modes as shown in figure
(a)

(b)

(i) If the frequency of the note produced in (b) is n, what is the frequency in case (a)?
(ii) In which case (a) or (b), is the note louder? Give reasons.
(iii) In which case is the pitch higher? Give reason.
Two waves of the same pitch have their amplitudes in the ratio 2 : 3.
(i) What will be the ratio of their loudness?
(ii) What will be the ratio of their frequencies?
