Q1) fill ups :-

a) the time period

b) time

c)

d) amplitude

e)

Q2) define :-

a) oscillation - the to - fro motion of pendulum at a periodic motion this is called oscillation.

b) amplitude - the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

c) time period - the time taken to complete 1 oscillation is known as time period.

d) Frequency- the number of wav.es that pas.s a fixed point in unit time; also, the number of cy.cles or vibrati.ons under.gone during one unit of time by a body in periodic motion.
