Physics Question on Waves
A sound wave is passing through air column in the form of compression and rarefaction. In consecutive compressions and rarefactions,
A
density remains constant
B
Boyle?? law is obeyed
C
bulk modulus of air oscillates
D
there is no transfer of heat
Answer
there is no transfer of heat
Explanation
Solution
There is no transfer of heat from compression to rarefaction as air is a bad conductor of heat. And time of compression/rarefaction is too small.
