Timing 50 oscillations instead of just one helps to reduce the impact of random errors and fluctuations in measurements. By averaging the total time taken for multiple oscillations, any anomalies from a single measurement are minimized, leading to a more accurate determination of the periodic time. This approach increases the precision of the results, as it provides a better representation of the system's behavior over time.
You look at the periodic table.
Look for predictable changes and patters.
look on the periodic table of the elements
The number one element on the periodic table is hydrogen. It is not a metal, but the lightest and most abundant element in the universe.

Vibration refers to mechanical oscillations about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road.sorce-wikipedia

Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.

Many oscillations are simple harmonic motions and such motion can be represented by a sine (or equivalently, cosine) curve.
The sine wave equation is y A sin(Bx C), where A is the amplitude, B is the frequency, and C is the phase shift. It is used to represent periodic oscillations in fields like physics, engineering, and music by showing how a wave varies over time. The equation helps to visualize and analyze the behavior of oscillating phenomena, such as sound waves, electrical signals, and mechanical vibrations.

periodic motion is a motion of body wich repeats itself in equal intervals of time , but a oscillatory motion is a periodic motion which is about a mean position . so all periodic motions could not be a oscillatory motion , but all oscillatory motions are periodic in nature.
You can measure the frequency of a pendulum's periodic motion by counting the number of complete oscillations it makes in a given time period, usually one second. The frequency is the number of cycles or oscillations per unit time and is usually measured in Hertz (Hz), which represents cycles per second.
