Question

The frequency of a wave is 4 Hertz. Find its time period.
​

Answer 1

Answer:

If the woodpecker drums upon a tree 4 times in one second, then the frequency is 4 Hz; each drum must endure for one-fourth a second, so the period is 0.25 s.

Answer 2

${\large{\bold{\rm{\underline{Given \; that}}}}}$

★ Frequency of a wave = 4 hertz

${\large{\bold{\rm{\underline{To \; find}}}}}$

★ Time period of the wave.

${\large{\bold{\rm{\underline{Solution}}}}}$

★ Time period of the wave = 0.25 seconds

${\large{\bold{\rm{\underline{Using \; concept}}}}}$

★ Formula to find time period

${\large{\bold{\rm{\underline{Using \; formula}}}}}$

★ Time period = ${\sf{\dfrac{1}{Frequency}}}$

${\large{\bold{\rm{\underline{Full \; Solution}}}}}$

~ As it's already given that the frequency is 4 hertz and we have to to find out the taken time so let's use the formula and do this question..!

⇒ Frequency = 4 hertz

⇒ Time period = ${\sf{\dfrac{1}{Frequency}}}$

⇒ Time period = ${\sf{\dfrac{1}{4}}}$

⇒ Time period = 0.25 seconds
