VIBRATION In this chapter you will learn about: Vibration Period and frequency Wave concept Transversal and longitudinal wave The relationship between frequency, wave velocity and wavelength Concept of wave in daily life
VIBRATION Consider figure The point b is called balance point The pendulum is said do one vibration if the pendulum moves from b-a-b-c-b Distance traveled by pendulum from balance point is called deviation. The largest deviation from balance point is called amplitude A-b or b-c is called amplitude • Vibration is a continuing periodic oscillationthrough is a balance point c a b
Vibration Period • Vibration period is time interval required to travel one vibration • T = t : n • T = vibration period • t = the time required • n = the number of vibration • Frequency is the number of vibration done by the body in one second • f =
