When the compression is incident on rigid wall it is reflected 1)Compression with a phase change of p. 2)Compression with no phase change. 3)Rarefaction with a phase change of p. 4)Rarefaction with no phase change
Answers
Explanation:
Therefore, a compression which is travelling towards the wall is reflected as a compression in the direction opposite to the wall and a rarefaction incident on the wall is reflected as a rarefaction. Hence, option A is correct.
Answer:
Option 2 : Compression with no phase change
Explanation:
Reflection of Sound Like light, the sound gets reflected at the surface of a solid or liquid. The directions in which the sound is incident and is reflected make equal angles with the normal to the reflecting surface at the point of incidence, and the three are in the same plane. Propagation of Sound Sound is produced by vibrating objects. The matter or substance through which sound is transmitted is called a medium. It can be solid, liquid, or gas. The eardrum senses the vibrations of sound, It sends the signals to the brain. This process is called hearing. The number of oscillations or vibrations per second is called the frequency of oscillation. The frequency is expressed in hertz (Hz). The larger the amplitude of vibration, the louder is the sound.
