When a particle, in a medium like water, is set into oscillatory motion, the neighbouring particles are also set into oscillatory motion due to the elastic forces. A wave disturbance starts spreading ...

IN an earlier communication 1 it was pointed out that, from a theoretical point of view, the cone-and-plate geometry was not a suitable one for the investigation of the linear time-dependent behavior ...

Any motion which repeats itself at regular intervals of time is known as periodic motion. If a body moves back and forth repeatedly about its mean position then it is said to be in oscillatory motion.
