Which of the following is not a longitudinal wave?

Which of the following is mechanical wave?

The persistence of sound in a hall is called

How many types of mechanical waves exist in physics?

A stone is dropped into a well and the sound of impact of stone with the water is heard after $$2.056\ \text{s}$$ of the release of stone from the top. If the acceleration due to gravity is $$980\ \text{cm}s^{-2}$$ and the velocity of sound in air is $$350\ \text{ms}^{-1}$$, then the depth of the well is

A man standing unsymmetrically between two parallel cliffs, claps his hand and starts hearing a series of echoes at intervals of 1 s. If the speed of sound in air is 340 m$$s^{-1}$$, then the distance between the two prallel cliffs, is

Surface waves strike the rock with their crests $$160\ m$$ apart. The velocity of the wave is $$40\ ms^{-1}$$, The time interval between two crests striking the rock is

Which type of wave is produced in the stem of tuning fork?

A wave passes from one medium to another medium. Which of the following quantity will change ?

The wavelength of waves produced on the surface of the water is $$20\ cm$$. If the wave velocity is $$24\ ms^{-1}$$, calculate the number of waves produced in one second.
