What adjustments would you make for tuning a stringed instrument for it to emit a note of a desired frequency?

What do you mean by pure tone? Which instrument can produce it?

A tuning fork of frequency 256 Hz produces 4 beats per second when sounded with a stringed instrument. What is the frequency produced by the instrument?

The diagram in Fig. shows three ways in which a string of length I in an instrument can vibrate. What is the ratio of frequency of vibrations in diagrams (i) and (ii) ?

An open pipe is 85 cm long. If the velocity of sound is 340 ms^(-1) , find the frequency of the fundamental note of the pipe. What would be the length of a closed pipe which produces a fundamental note of the same frequency?

An open pipe produces fundamental note. All of a sudden one of its ends is closed. If again fundamental note is emitted, the frequency of the note will be :

A siren emitting a sound of frequency 1000 H_(Z) moves away from you towards a cliff at a speed of 10 m//s . (a) What is the frequency of the sound you hear coming directly from the sirven ? (b) What is the frequency of sounds you hear reflected off the cliffb ? (c) What beat frequency would you hear ? Take the speed of sound in air as 330 m//s .

A siren emitting a sound of frequency 2000 Hz moves away from you towards a cliff at a speed of 8 m/s. (a) What is the frequency of the sound you hear coming directly from the siren. (b) What is the frequency of sound you hear reflected off the cliff. Speed of sound in air is 330(m)/(s) .

The diagram in Fig. shows three ways in which a string of length I in an instrument can vibrate. Which vibration has a frequency four times that of the first?

An ac generator G with an adjustable frequency of oscillation is used in the circuit, as shown. To increase resonant frequency of the circuit, some of the changes in the circuit are carried out. Which changes would certainly result in the increase in resonnatn frequency ?
