Question

Frequency of 1Hz corresponds to ______________?

Answer 1

Hint:in order to know what frequency of 1Hz corresponds to first of all we need to know what is frequency. Frequency is nothing but the number of occurrences of an event which is repeating itself per unit time. Along with this frequency have a relationship with time period which help us to solve most of the frequency related problems in physics.

Formula used:
$\text{frequency = }{\displaystyle \frac{\text{number of vibration}}{\text{time}}}$
This is the relation between frequency and number of vibrations per time. Which clearly states that frequency is directly proportional to number of vibration and is indirectly proportional to time

Complete answer:
Frequency is measured in Hz. Hz stands for hertz which is equal to an event happening per second. Hertz was actually named after a physicist named Heinrich Hertz by IEC in 1930. IEC stands for International Electrotechnical Commission.Frequency of 1Hz corresponds to one cycle per second.

Example: As we know 1Hz is equal to one cycle per second but if a coil makes two cycles in a second then frequency will be 2Hz. If it makes 3 vibrational cycles in a second, then frequency will be 3Hz.for 8 cycles in 4 second frequency will be 2Hz.

This diagram shows how frequency is depicted in the form of a wave. This also shows us that in a cycle there is an upper crest and a lower crest. Upper crest and lower crest are the point where the highest point and the lowest point.

Note: Most of the people are confused about frequency with speed but they are totally different. Speed refers to how a fast moving object is travelling distance in a specific time but frequency measures how many cycles are covering in specific time which involves the crest so it doesn’t.
