Ques. the frequencies of sounds produced from two
different sources in medium p are 340hz and 400 hz
and the difference of their wavelengths is 0.165 m. in
another medium q the velocity of sound is 400ms.
[r. b.-2017]
a. what is called contact force?
b. explain the relation between the velocity of
sound with the nature of medium.
c. find out the velocity of sound in medium? 3
d. if the difference of wavelength of same sound in
both media is 0.1m, then will the wave travel the
distance 124 m in medium q by 80 complete
vibrations? give opinion through mathematical
analysis.
