A pendulum is a weight suspended from a pivot so that it can swing freely. ... When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period.

Area :- Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object.
Density :- The density, of a substance is its mass per unit volume
Wavelength :- the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Pendulum :- a weight hung from a fixed point so that it can swing freely, especially a rod with a weight at the end that regulates the mechanism of a clock.
Range :- the area of variation between upper and lower limits on a particular scale.
