If you pluck harder on a guitar string, or forcefully hit a drum, the sound will be louder. (True or False)

If the vibrations of a vibrating body are fast then the sound is said to be high-pitched. (True or False)

The plucked string of a guitar has vibratory motion .

You will always be able to see vibrations in an object. (True or false)

A sound is produced by plucking a string in a musical instrument, then

Statement I : When a guitar string is plucked , the frequency of the plucked string will not be the same as the wave it produces in air . Statement II : The speeds of the waves depend on the medium in whhich they are propagating.

If you strike a tuning fork hard, you get a louder sound.

A sound source of frequency 512 Hz is producing 6 beats with a guitar. If the string of gultar is stretched slightly then beat frequency decreases. The original frequency of guitar is

A closed organ pipe is sounded near a guitar, causing one of the string to vibrate with large amplitude . We vary the tension of the string until we find the maximum amplitude. The string is 80% as long as the closed pipe. If both the pipe and the string vibrate at their fundamental frequency, calculate the ratio of the wave speed on the string to the speed of sound in air.

Two identical violin strings, when in true and stretched with same tension , have a fundamental frequency of 440.0 H_(Z) . One of the string is retuned by adjusting its tension . When this is done, 1.5 beats per second are heard when both strings are plucked simultaneously. (a) What are the possible fundamental frequencies of the retuned string? (b) by what fractional amount was the string tension changed if it was (i) increased (ii) decreased?

Write 'true' or 'false' for the following statement : With the increase in the frequency of a body, the sound becomes shrill.
