Answer:
A Longitudinal Wave is _____.
D.a wave that the medium is displaced parallel to the direction of the wave, such as a sound wave in the air
Explanation:
Sound : It is the mechanical energy that causes sensation of hearing to the ear.
Sound is produce by the vibrating objects .
Vibration : To and fro motion of the object.
The vibrating motion of particle creates two region of air pressure:
- Compression : A region of high - pressure
- Rarefaction : A region of low- pressure
Hence , Sound wave travels by forming compression and rarefaction.
This disturbance in particles of air is called : Wave
The waves are classified into two parts :
1. Longitudinal wave : These are those waves in which particles of medium travel parallel to the propagation of the wave.They both <u>travel in same direction.</u>
<u>Sound wave </u>is longitudinal wave
2. transverse wave : These are those wave in which particle of medium travel perpendicular to the direction of wave . If particles travel along x-axis then wave along y or z- axis.
example : Light (or electromagnetic wave) is transverse wave
