Assertion. Tympanic membrane separates the external ear from the middle ear. Reason. Tympanic membrane transmits vibrations (pressures waves in air) to the internal ear via ear ossicles of middle ear.

Assertion : Hair cells on the basilar membrane (organ of Corti) are responsible for hearing. Reason : Pressure waves, which begin at the oval windows, cause the basilar membrane to vibrate so that the cilia of the hair cells touch the tectorial membrane. This causes the hair cells to initiate nerve impulses, which are carried by the auditory nerve to the brain.

A sound wave is travelling in a medium.If equation of displacement wave in the medium is given by y = 2cos ( 2 pi x - 100 pi t + pi/2 ) then equation of pressure waves will be (B rarr Bulk modulus of medium) (А) P = 4B pi sin ( 2 pi x - 100 pi t ) (В) P = 4B pi sin ( 2 pi x + 100 pi t ) (C) P = 4B pi cos ( 2 pi x - 100 pi t ) (D) P = 4B pi cos ( 2 pi x + 100 pi t )

What is the phase difference between the displacement wave and pressure wave in sound wave :-
