Question

A wave has a time period of 0.2 s Calculate the frequency of the wave.

Answer 1

`\boxed{\sf Frequency \ (f) \ of \ the \ wave = 5 \ Hz}`

Given:

Time Period (T) = 0.2 s

To Find:

Frequency (f) of the wave

Step-by-step explanation:

`\sf Frequency (f) = (1)/(Time Period (T))`

`\sf f = (1)/(0.2)`

`\sf f = (1)/(0.2) * (10)/(10)`

`\sf f = (10)/(2)`

`\sf f = \frac{ \cancel{2} * 5}{ \cancel{2}}`

`\sf f = 5 \: Hz`

Answer 2

`\huge\boxed{f = 5\ Hz}`

Explanation:

Given:

Time period = T = 0.2 sec

Required:

Frequency = f = ?

Formula:

f = 1/T

Solution:

f = 1/0.2

f = 5 Hertz
