Answer:
<em>Time period of pendulum is 2.02 s.</em>
Explanation:
A <em>simple pendulum</em> is a device which consists of mass m hanging from the string of length L attached to the some point.When displaced and released its swings back and forth with periodic motion.
The time period of pendulum is defined as time taken by the pendulum to complete one full oscillation . it is denoted by T.
By <em>Huygens law of period of pendulum</em>,
T = 2π
eqn 1
where L is the length of pendulum,
g is acceleration due to gravity
<em>Period of pendulum is independent of the mass of pendulum,</em>
<em />
Substituting values in eqn 1
T = 2π 
T = 2.02 s
<em>Time period of pendulum is 2.02 s.</em>
Answer:
the action of polarizing or state of being or becoming polarized: such as the action or process of affecting radiation and especially light so that the vibrations of the wave assume a definite form. Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. There are two types of waves, transverse waves, and longitudinal waves.
