What is a period in physics?
Period refers to the time that it takes to do something. When an event occurs repeatedly, then we say that the event is periodic and refer to the time for the event to repeat itself as the period. The period of a wave is the time for a particle on a medium to make one complete vibrational cycle.
How do you find the period of a motion?
The angular frequency depends only on the force constant and the mass, and not the amplitude. The angular frequency is defined as ω = 2 π / T , ω = 2 π / T , which yields an equation for the period of the motion: T = 2 π m k .

How do you find the time period for Class 7?
(3) Time-Period To find the time taken by one oscillation (or time period), we measure the time taken by a large number of oscillations. Dividing the total time by the total number of oscillations, we get the time for one oscillation (or time-period) of the pendulum.
How to find period of a wave?
The formula for the period is used to calculate the time period of a wave. It is the time taken by a wave to reach from one peak to another. A periodic function is defined as a function that repeats its values at regular intervals or periods. The period of a function f (x) is p, if f (x + p) = f (x), for every x. Let us learn about the formula for the period with a few solved examples in the end.
What is Formula for Period?
According to the definition of a period of a function, a function f (x) will be periodic with period p, so if we have f (x + p) = f (x), for every p > 0. The period of each of sin x, cos x, csc x, and sec x = 2π. The period of each of tan x and cot x = π. The period of the wave decreases as its frequency increases. Here is the formula for period (T) of a trigonometric function:

Example: The period of tan 3x using the period formula is π / 3. You can observe this from the following graph also.
How are frequency and period related?
As previously stated, the frequency and period of a wave are closely related. Frequency describes how often, or how frequently, a wave will go through its cycle in a given amount of time , while period describes how long it takes for a wave to complete one cycle. Therefore, if a wave has a shorter period, meaning it can complete a cycle in a short amount of time, then more cycles can pass in a given timespan, thus increasing the frequency. In other words, with a lower period, a wave will have a higher frequency and vice versa. In the math world, these two are said to be inversely proportionate with one another, where the value of one goes up while the other goes down.
What is the Period of a Wave?
Waves are also present in ways that their structure can not be seen from the naked eye, like sound waves or electromagnetic waves (light). They have specific properties that make them unique: a high point and low point that oscillate in a continuous cycle .
How to find frequency of a wave?
Frequency can be found by taking the velocity of a wave ( {eq}v {/eq}) and dividing it by its wavelength ( {eq}lambda {/eq}):
How many cycles does a wave have?
Since the wave can complete one cycle in two seconds, then it would complete five cycles in ten seconds. This means that the wave has a frequency of five cycles over a timespan of ten seconds. However, frequency is typically measured in the number of cycles that occur over just one second, so this wave's frequency would be one-half cycles per second. In other words, this wave can only complete half of its cycle in one second.
How many cycles does a wave have per second?
Therefore, the wave has a frequency of three cycles per second. Now the inverse of this frequency can be taken to determine the period:
What is the property of a wave?
Another property of a wave is its frequency . Similar to a wave period, the wave's frequency has to do with time and the wave cycle. However, frequency refers to how many wave cycles pass in a given timespan.
How long does a wave cycle last?
The wave has a period of 1/3, meaning it completes a full cycle in only one-third of a second.

What is the relationship between frequency and period?
Relationship between Period and frequency is as under : The frequency of a wave describes the number of complete cycles which are completed during a given period of time. As such, frequency is a rate quantity which describes the rate of oscillations or vibrations or cycles or waves on a per second basis.
What is the reciprocal of frequency?
Explanation: Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
