Body has its own frequency

Physics is how much great, do you think? Physics also describe about natural frequency of a body. Also we must know about the natural frequency of a body. The every body in the universe has characteristic tendency to vibrate when an external periodic force is applied. The vibration of the body depends upon their dimension and elastic property of the body. Such a natural characteristic frequency of vibration of the body is known as natural frequency of the body. The natural frequency depends upon the nature of the body i.e. it depends upon the shape, size and elastic property of a body. Hence also our universe is regularly vibrate on their own axis due to its natural frequency.
