Amplitude, Time Period and Frequency of a Vibration

Differentiate between vibration and oscillation.

What type of vibrations cause a loud sound?

Explain why some sounds are loud and other sounds are quiet.

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.

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)

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

Time taken to complete one vibration is called

The pitch of sound depends on the amplitude of vibrations.

A tuning fork makes $100$ oscillations in one second. It vibrates with a frequency of $50 \mathrm{Hz}$.

The membrane of a table is tightened to _____ the pitch of the sound.

The loudness of a lion’s roar is much greater than a bird’s chirp. What causes the difference in the loudness?

The harder you beat a table, louder is the sound. List two reasons for it.

An ambulance with its siren sounding is standing in heavy traffic. A pedestrian notices that although the loudness of the sound produced does not change, its pitch varies. Which option in the following is responsible for the change in its pitch: Amplitude, frequency ?

The unit of frequency is hertz.
