Amplitude, Time Period and Frequency of a Vibration

Musical instruments can be played at different pitches by changing the _____ of its string.

Name the following.

Frequency is calculated as the inverse of this physical quantity.

The maximum distance from the mean position of a vibration is known as its amplitude.

Why is the roar of our national animal different from the sound of a mosquito?

The buzzing sound of mosquito is produced when it vibrates its wing at an average rate of $600$ vibrations per second. Time period of the vibrations of each wing is $16.67\times {10}^{-\mathrm{A}} \mathrm{s}$. Value of $\mathrm{A}$ is 

Define oscillatory motion. Explain what is frequency.

The to and fro motion of an object is called _____ motion. (Oscillatory, circular)

Voice of which of the following is likely to have a minimum frequency?

The loudness of a sound depends on the _____ (frequency/amplitude) of the vibrations that produce it.

Conduct an experiment to Identify pitch or shrillness of different sounds.

The sound from an insect is produced when it vibrates its wings at an average rate of $500$ vibrations per second: What is the frequency of the vibrations in hertz?

(Answer should contain, only magnitude of frequency)

Define

period of $\mathrm{S}.\mathrm{H}.\mathrm{M}.$

Write the definition of pitch. Differentiate the reason between grave and shrill sound.

Time taken to complete one vibration of a vibrating object is called_____.

SI unit of frequency is

Define frequency and periodic time? Represent the relation between them by a formula.

The loudness of sound depends on _____.

The unit of the loudness of sound is decibel $\left(\mathrm{dB}\right)$.       

Time taken to complete one vibration is called
