Sound Test - 28...

Time period of a sound wave is $$10\ ms$$. What is the frequency of the sound wave?

If velocity of sound in air is 340 $$m  s^{-1}$$, calculate frequency when wavelength is 0.85 m :

In the bell jar experiment, as air is removed from the jar :

The loudness of sound is determined by the

If a wave completes 20 vibrations in 2.5s, then its frequency is

A tuning fork makes $$256$$ vibrations per second in air. When the speed of sound is $$330 \ m/s$$, the wavelength of the note emitted is :

1 hertz is equal to

Lightning can be seen the moment it occurs. Paheli observes lightning in her area. She hears the sound 5 s after she observed lightning. How far is she from the place where lightning occurs? (Speed of sound $$= 330$$  m/s)

A sound wave travels at a speed of 339 m/s . If its wavelength is 1.5 cm , what is the frequency of the wave?

Pitch of sound is determined by its
