When a tuning fork vibrates, the waves produced in the fork are

Eardrum is a part of 

The sound in the audible range is called 

Relation between frequency and time period is 

The sound of frequency less than $$20\ Hz$$ is known as:

A pendulum oscillates $$20$$ times in $$2$$ seconds then its time period is 

The loudness and pitch of a sound depends on:

In a clock, the time period of hour hand is :

The speed of a wave is $$ 350\, m/s $$ and its wavelength $$ 50\,cm $$ , then the frequency of the wave will be :

In longitudinal waves, the vibration of the particles of the medium:
