Question

Calculate the period and frequency for the second hand, minute hand, and hour hand of a clock.​

Answer 1

Answer:

Periods are 60 seconds, 60 minutes and 12 hours frequency are their reciprocal.

Answer 2

For second hand, 60 s, 0.0166 Hz.

For minute hand, 3600 s and $2.77 \times10^-^4 Hz$

For hour hand, 43200 s and $2.3 \times10^-^5 Hz$

Explanation:

The time period and frequency relation is given as

$f=\frac{1}{T}$

Here, T is the time period and f is the frequency.

Now time period for the second hand is = 1 min = 60 s.

So frequency,

$f_s=\frac{1}{60s}$

$f_s=0.0166 Hz=1.67\times10^-^2Hz$

Time period of minute hand = 1 hour = 3600 s.

so frequency,

$f_m=\frac{1}{3600s} = 2.77 \times10^-^4 Hz$

Time period of hour hand = 12 hour = 43200 s.

so frequency,

$f_h=\frac{1}{43200s} = 2.3 \times10^-^5 Hz$
