Statement-I: Compression and rarefaction involve changes in density and pressure of medium.
Statement-II: When particles are compressed, density of medium increases and when they are rarefied, density of medium decreases.
(1) Both Statement-I and Statement-II are correct.
(2) Both Statement-I and Statement-II are incorrect.
(3) Statement-I is correct but Statement-II is incorrect
(4) Statement-II is correct but Statement-I is incorrect
