Sound Part 2

In which of the following part of brain, the nerve impulses of sound are analysed ?

A car is moving towards a high cliff. The car driver sounds a horn of frequency f . The reflected sound heard by the driver has a frequency 2 f . if v be the velocity of sound, then the velocity of the car, in the same velocity units, will be

The minimum wavelength of sound that is audible to a person is (speed of sound is 340 m/s)

Assertion : Sound waves cannot be polarised. Reason : Sound waves are longitudinal in nature.

A man holding a sound source at the top of a tower emitting frequency of sound as v=1000Hz . Suddenly it slips from his hand and falls down with 'g' acceleration. The frequency of sound heard by the man at t=4sec . (Velocity of sound =320m//s , g=10m//s^(2) )

Statement 1: Sound waves can not propagate through vacuum but light waves can. Statement 2: Sound wave can not be polarised but light waves can be.

Sound from coherent sources S_(1) and S_(2) are sent in phase and detected at point P equidistant from both the sources . Speed of sound in normal air in V_(0) , but in some part in path S_(1) , there is a zone of hot air having temperature 4 times , the normal temperature , and width d . What should be minimum frequency of sound , so that minima can be found at P ?

coordination part 2

The velocity of sound in hydrogen at STP is 1400ms^(-1) . Find the velocity of sound in a mixture with 3 parts by volume of oxygen and 2 parts by volume of hydrogen at 819^(@)C ?
