Question

Define time period and frequency give the SI unit

Answer 1

$\underline\bold{Time\: Period}$


For a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given period of time.

S.I. unit is $\bold{Second}$


$\underline\bold{Frequency}$


So while wave frequency refers to the number of cycles occurring per second, wave speed refers to the meters traveled per second.

S.I. unit is $\bold{Hertz}$

Answer 2

Time period.

A time period is the time needed for one complete cycle of vaibration to pass in a given point. As the frequency of a wave increases, the time period of the wave decrease. The unit for time period is ‘Second’.Frequency and time period relationship that can be expressed mathematically

as T = 1/F or as F = 1/T

Frequency.

The SI unit of frequency is Hertz (hz), named after the German physicist Heinrich hertz. one hertz repeats once per second.
