What is frequency and its types?
Answers
Answer:
Frequency refers to a measure of how often something has happened. ... The different types of frequency distributions are ungrouped frequency distributions, grouped frequency distributions, cumulative frequency distributions, and relative frequency distributions.
Explanation:
Answer:
The frequency is the parameter which explains the phenomenon of oscillatory and vibration like the mechanical vibration, sound signals, light, frequency waves etc. The term “period” represents the time required by the wave for one oscillation, i.e., it is inversely proportional to the frequency.
Frequency is the total number of oscillations per unit time. If we take the example of the flashes, then the period is the time between the two flashes. And the frequency is the total number of flashes per second.
Relation Between Wave δ Frequency
The wave is a kind of disturbance used for transferring the information. The information is transferred in the form of the oscillations. The wave period and the wave frequency are the two phenomena of the oscillations. The wave period is the difference between the wave and the wave frequency is the number of waves per units time.

Types of Frequency
The frequency is mainly classified into two categories.
1. Angular Frequency – The angular frequency shows the number of revolution at the fixed interval of time. The unit of angular frequency is Hertz. The relation between the frequency and angular frequency is expressed as;frequency-equation
Where, ω – angular frequency
2. Spatial Frequency – The frequency which depends on the spatial coordinate is known as the spatial frequency. It is inversely proportional to the wavelength. The spatial frequency measures the characteristic of the structure that is periodic in space.
