Question

A body of frequency “f” would complete one vibration in a)f seconds b)1/f sec c) 1sec ?

Answer 1

b) `1/f` second

Explanation:

Frequency: Number of vibrations occuring in 1 second.

Unit of Frequency: `"second"^-1` (or) Hz

Time period: Time taken for one vibration.

Unit of time period: `"second"`

Relationship between frequency and time period

`"Time period" = 1/"Frequency"`

∴ For given frequency “f Hz” time period is `1/f` second
