Introduction to longitudinal mechanical waves:
A mechanical wave is a periodic disturbance which can be produced only in a material medium and it transfers energy from one point to medium and it transfers energy from one point to another without there being a direct contact between the two points.
Longitudinal waves are one of the types of mechanical waves. If the particles of the medium forward and backward along the same direction in which the energy propagates then the wave is known as the longitudinal wave.
Sound waves in air and the waves produce in a spring when it is pushed and pulled are examples of the longitudinal waves.Having problem with Wave Theory of Light keep reading my upcoming posts, i will try to help you.
Description of longitudinal waves with example
Consider a gas or air enclosed in a cylinder. The vertical lines represent different layers of the air in undisturbed position when no energy is travelling through it. Now when a longitudinal wave is sent through the medium, the layers of the air begin to vibrate in the same direction as the direction of the propagation of energy. In doing so a certain number of neighboring layers are brought closer together. At these points the pressure increases and a compression is set up.
Looking out for more help on fahrenheit to celsius equation in physics by visiting listed websites.
Compressions and rarefactions in longitudinal waves
At fixed distances compressions the layers are moved apart. Here the pressure decreases and a rarefaction is set up. As the energy propagates the compressions change to rarefactions and vice verse and they are equal spaced. The distance between the centers of consecutive compressions or consecutive or consecutive rarefactions is the wave length of a longitudinal wave. All other definitions given for transverse waves are valid for longitudinal waves as well. The longitudinal waves consist of alternate compressions and rarefactions. The maximum displacement of a layer on either side of its mean position is the amplitude of the longitudinal wave. The number of complete vibrations of the layers of the air in one second represents the frequency of the wave.
